■ Supports 45W or up application circuit designs
■ Supports 10mV DLNK voltage step requests required
by USB PD programmable power supply (PPS) or
other proprietary rapid charge protocols
■ RC charging VCC technology enables ultra-low no-load
power of <75mW with ample margin at 230VAC and 5V
output voltage setting
□ <20mW achievable (at 230VAC/5VOUT) with an
external active startup circuit
■ High VCC pin voltage rating eliminates external VVCC
LDO
■ Tight multi-level constant-voltage and multi-level constantcurrent
regulation with primary-side feedback and control
■ Proprietary optimized load adaptive maximum
constant frequency PWM switching with quasiresonant
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
■ No audible noise over entire operating range
■ User-configurable 4-level cable drop compensation
independent of output voltage
■ Proprietary secondary-to-primary digital communication
with single optocoupler for all the rapid charge information:
□ Output voltage request
□ Output current limit
□ Output voltage undershoot detection for fast
dynamic load response
□ Over-voltage protection
■ EZ-EMI TM design enhances manufacturability
■ Built-in single-point fault protections against output
short-circuit including soft short and half short, output
over-voltage, and output over-current
■ Advanced fault control technology addresses issues of soft
shorts in cables and connectors by effectively reducing the
average output power at fault conditions without latch
■ Dual over-temperature protection with both internal
OTP and external shutdown control
■ DET pin provides VVIN OVP or X-cap discharge protection
