■ 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 noload

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 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 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-EMITM 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

■ Over-temperature protection with internal OTP control
