■ 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.
