● 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
