● Integrated XM-Comm technology eliminates

secondary-to-primary optocoupler

● Transformer communication for all the rapid charge

information: output voltage request, output current

limit, output voltage undershoot, and over-voltage

protection

● Source charging VCC technology eliminates the active

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

consumption (< 20mW) at 230VAC with typical 5V/2A

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

● 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-EMI? 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

● SmartDefender+TM 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 AFC,

QC 2.0 and 3.0 technologies, FCP, etc.
