● Supports 45W or up application circuit designs

● Supports 10mV voltage step request up to 21V

required by USB PD programmable power supply

(PPS) or other proprietary rapid charge protocols

● Integrated XM-Comm technology eliminates

secondary-to-primary optocoupler

x Transformer communication for all the rapid charge

information: output voltage request, output current limit,

output voltage undershoot, and over-voltage protection

● RC charging VCC technology enables ultra-low no-load

power of < 75mW with ample margin at 230VAC and 5V

output voltage setting

x < 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

● Fast dynamic load response (DLR)

● Proprietary optimized load adaptive maximum constant

frequency PWM switching with quasi-resonant operation

achieves best size, efficiency, and common mode noise

● Multi-mode PWM/PFM control improves efficiency at

various load conditions

● User-configurable 4-level cable drop compensation

independent of output voltage

● 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

● Advance 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

● No audible noise over entire operating range

● Supports rapid charge technologies, such as QC 2.0

and 3.0 technologies, FCP and USB PD
