IW1782集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

● 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
