● Supports rapid charge technologies such as
Qualcomm® Quick Charge™ 3.0 (QC3.0) technology
to provide 3.6V to 12V in 200mV increments with userselected
various output current limit combinations
● Proprietary secondary-to-primary digital
communication and built-in decoder eliminate discrete
decoder and significantly simplify system design
● Single opto-coupler for all the rapid charge information:
output voltage request, output current limit, output
voltage undershoot, and over-voltage protection
● Tight multi-level constant-voltage and multi-level
constant-current regulation with primary-side feedback
and control
● Ultra-low no-load power consumption with lowest
system cost (<10mW at 230VAC with typical 5V2A
setting using Schottky diode rectifier; <20mW at
230VAC with typical 5V2A setting using synchronous
rectifier)
● Fast dynamic load response (DLR) with secondaryside
load transient detection
3 Applications
● Rapid-charging AC/DC adapters for smart phones,
tablets and other portable devices (3.6V-12V, 1A-3A).
● Proprietary optimized load adaptive maximum
constant frequency PWM switching with quasiresonant
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™ smart hiccup technology
helps address issues of soft shorts in cables and
connectors by effectively reducing the average output
power at fault conditions without latch
● User-configurable external shutdown control
● No audible noise over entire operating range
