The product is a highly integrated PD controller. It complies with the latest USB Type-C and PD
3.1 standards and supports BC1.2 and the most popular high voltage fast charging protocols with a
DPDM interface. Its target for notebooks, dongles, monitors, power banks and power adapters.
The SW2505 integrates a 32-bit, up to 40-MHz ARM Cortex-M0 processor with 128-KB flash, 4-
KB SRAM, 21 GPIOs, timers, I2C and a UART interface, 12-bit ADC, VBUS discharging path, 12-
bit DAC for VBUS regulation to support wide operation voltage range with 30V maximum rating, gate
driver to control external VBUS NMOS FET, and protection circuits.
