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