Product：BCM6135, DC-DC Bidirectional Power Converter Module

Recommended reasons： The Vicor BCM6135 is a fully functioning 800V (High Voltage (HV)) – 48V (Safe Extra Low Voltage (SELV)) DC-DC converter that provides up to 2.5kW of power from a module weighing 58g in a package of 0.016L. The BCM6135 provides both the voltage conversion and the electrical isolation between HV and SELV inside of a miniature package. In addition to the size and weight advantage, the BCM6135 is symmetrically bidirectional. It is able to achieve a current slew (transient) rate of 8.0M A/s – faster than any load in a vehicle and the fastest in the automotive industry. The BCM6135 enables OEMs and Tier Ones solve decades-old power challenges. OEMs can add new functions like active suspension, optimize vehicles with a 48V zonal power architecture or delete the 48V battery. Its compact size can reduce power system volume by nearly 50%. The Vicor BCM6135 is the only DC-DC for HV to SELV that utilizes the proprietary Sine Amplitude Conversion (SAC) process and patented topography for the voltage switching. The SAC process as executed in the BCM6135 is a Zero Voltage Switching method that facilitates advantages in switching speed, efficiency and transient performance. Vicor has developed these processes and supporting hardware to miniaturize the DC-DC into the smallest package in the industry. The SAC technology imparts the BCM6135 with these key performance benefits a) The BCM6135 achieves a 33% higher peak efficiency of 97.3% vs the current best in class solutions. b) SAC allows a switching frequency of 1.3MHz, double the frequency of GaN devices that are entering the market. c) Unlike the standard discreet device based DC-DC, the BCM6135 can uniquely produce the same peak power in either direction, bucking 800V – 48V or boosting 48V - 800 V. d) SAC empowers the BCM6135 to achieve an astounding current slew (or transient) rate of 8.0M A/s. It transitions from forward to reverse processing with no delay. e) The BCM6135 provides internally the HV to SELV isolation, maintaining a 4242VDC input to output Isolation f) Capacitance multiplication of 256 is achieved between the high and low voltage busses, reducing the number of size and number of external capacitors required g) The high slew rate and capacitance multiplication enable the creation of a virtual 48V battery, eliminating the need for a physical 48V battery in the vehicle—unique to this product.

Chipone Technology （Beijing）Co., Ltd.

Product：iML8986 Power Management IC for TFT LCD Panels

Recommended reasons： The previous process design involved separating the PMIC and L/S (Level Shifter) into separate dies (dual die) due to the complexity of L/S operations ranging from negative voltage -20V to high voltage +40V. However, this dual die design resulted in higher costs and lower yield compared to the one-die solution. Integrating the PMIC and L/S into a single die (one-die solution) reduces packaging costs, improves production yield, reduces customer returns, and avoids process issues caused by a one of die's production capacity problems. The integration of the PMIC and L/S into a one-die solution represents a higher level of technology and is a future trend towards highly integrated one-die solutions. The iML 8986 is a highly integrated power management IC for TFT LCD panels and customized for panel manufacturer AUO. It is positioned for mid-to-high-end MNT and TV applications. AUO, as a company specializing in display technology and electronic products, holds a leading position in LCD panels. The device consists of one current mode boost regulator for AVDD, 3 current mode buck regulators for DVDD1, DVDD2 and DVDD3. An inverting regulator for VGL, two negative linear regulators (VSSG_P, VSSQ_P), a boost regulator for VGH with temperature-compensated output, 3-channel programmable amplifiers and an internal voltage detector. Additionally, it incorporates a 12-channel level-shifter scan driver for driving TFT panels. AUO considers the power management IC as key part, and for the iML 8986, we offer superior static quiescent current consumption compared to competitors, better efficiency under maximum applied loads in MNT, lower temperature on the panel, and flexible and wide SR adjustments to help customers avoid system EMI interference on HC. The AVDD Vpp performance of the iML 8986 surpasses competitors in both BOOST and SEPIC modes. All these advantages are combined in our one-die solution, demonstrating strong competitiveness in terms of pricing. Therefore, the iML 8986 has a great opportunity to become the first key part PMIC for AUO in Chipone

Product：InnoMux™-2 1700V

Recommended reasons： InnoMux-2 1700 V is a single-stage, independently-regulated, multi-output offline power supply IC with a gallium nitride switch rated at 1700 V outputs that provides a new way to design multi-output PSUs. InnoMux-2 ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently-regulated voltage outputs or two voltage output and a constant current output. Elimination of separate DC-DC stages slashes component count, reduces PCB footprint and increases efficiency by as much as 10 percent compared to traditional two-stage architectures. InnoMux-2 ICs deliver up to 90 watts of output power with accurate regulation of better than ±3 percent across the full input line, load, temperature and differential current step conditions. Total power system efficiency (AC to regulated low-voltage DC segment) is above 90 percent; the advanced InnoMux-2 controller also manages light-load power delivery, avoiding the need for pre-load resistors and reducing no-load consumption to less than 30 mW. This conserves power for necessary functionality in applications subject to the 300 mW allowance for standby usage under new international regulations. The 1700 GaN switch – easily industry’s highest voltage rating - easily supports 1000 VDC nominal input voltage in a flyback configuration and replaces expensive silicon carbide (SiC) transistors in power supply applications such as automotive chargers, solar inverters, three-phase meters and a wide variety of industrial power systems. Most electronic devices already operate using multiple internal DC voltages. For example, a television requires multiple voltage rails to supply the image processor, audio amplifier and LED backlight. The integration of brushless DC motors, network connectivity and enhanced user interfaces into white goods—aimed at enhancing user experience and efficiency—also necessitates extra voltage rails. While a conventional refrigerator might use 25V to power its icemaker, newer models may also require a constant current output for an LCD display's backlight and a lower voltage, such as 5 V, for a microcontroller unit (MCU) to operate a microprocessor. Governments globally have pledged to lower carbon dioxide emissions to address climate change. This means that the efficiency of a solution during low load operations is increasingly scrutinized. Transitioning to an InnoMux-2 based solution could enhance overall efficiency by 5% to 10%, eliminate the need for a bleed resistor and address the standby power limitations. According to analysts at Yole, the Power GaN device market is poised to reach $2 billion by decade's end, expanding across various application spaces with potentially attractive cost advantages over SiC. The combination of the new approach to delivering accurate, multi-output power supplies with the 1700 V GaN switch means that many more markets can benefit.
