■ Supports 45W or up application circuit designs

■ 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

■ 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

■ 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 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

■ Over-temperature protection with internal OTP control

■ No audible noise over entire operating range

■ Supports rapid charge technologies, such as QC 2.0

and 3.0 technologies, etc.
