Features

? Integrated secondary-side flyback controller and charging port controller

? Integrates secondary side synchronous rectifier (SR), PWM control with ACF support

? Supports synchronous rectification in critical conduction mode (CrCM), valley switching, discontinuous

conduction mode (DCM), and continuous conduction mode (CCM) and supports switching frequency up to

300 kHz

? Supports burst mode for light load operations

? SR driver works with both standard MOSFET and logic level MOSFET

? USB PD 3.1 compliant with EPR support of up to 28 V VBUS

? Supports USB PD 2.0, PD 3.0 with Programmable Power Supply (PPS), QC5.0, QC4+, QC 4.0, QC 3.0, QC 2.0,

Samsung AFC, Apple Charging, and BC v1.2 charging protocols

? Integrates low-side current sense amplifier (LSCSA), 2x VBUS discharge FETs, and an NFET gate driver to drive

the load switch and VCONN FETs to support EMCA cables

? Configurable VBUS overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP),

short-circuit protection (SCP), and system overtemperature protection (OTP)

? Protects against accidental VBUS to CC short; electrostatic discharge (ESD) protection on CC, VBUS, and DP/DM

lines and overvoltage on DP/DM lines

? Integrates a 32-bit Cortex?-M0+ with 64-KB flash, 8-KB SRAM, and 64-KB ROM

? 32-pin QFN package with –40°C to +150°C junction temperature range
