● Supports10mV DLNK voltage step request required

by USB PD programmable power supply (PPS) and

other proprietary rapid charge protocols

● Source charging VCC technology eliminates the active

start-up (ASU) and maintain ultra-low no-load power

consumption (< 20mW) at 230VAC with typical 5V

output setting

● High VCC pin voltage rating eliminates external VCC

LDO

● Tight multi-level constant-voltage and multi-level

constant-current regulation with primary-side feedback

and control

● Proprietary optimized load adaptive maximum constant

frequency PWM switching with quasi-resonant

operation achieves best size, efficiency, and common

mode noise

● Backward compatible with QC2.0/3.0 and other

proprietary rapid charge protocols with secondary-side

interface circuits

● Multi-mode PWM/PFM control improves efficiency at

various load conditions
