特性 Features

? Integrated secondary-side flyback controller and charging port controller

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

? Supports synchronous rectification in quasi-resonant (QR) or 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

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
