● AccuSwitchTM technology - integrated 700V power

MOSFET

● 25W output power capable

● iW1825-01 and iW1825-31 options: external

supplemental output over-voltage protection

● iW1825-10 options: external input over-voltage

protection

● Adaptively controlled soft-start enables fast and

smooth start-up into large capacitive loads (from

330μF to 6,000μF)

● Internal single-point fault protections against output

short-circuit, output over-voltage and output over-current

● User-configurable light-load operation mode for

optimized dynamic load response and no-load power

consumption

● < 75mW no-load power consumption at 230VAC with

fast dynamic load response in typical 12V, 2A 24W

compact adapter/charger

● PrimAccurateTM Primary-side feedback eliminates

optocouplers and simplifies design

● Proprietary optimized 79kHz maximum PWM switching

frequency with quasi-resonant operation achieves best

size, efficiency and common mode noise

● EZ-EMI? design enhances manufacturability

● Adaptive multi-mode PWM/PFM control improves efficiency

● User-configurable 5-level cable drop compensation

provides design flexibility in iW1825-01 and iW1825-31 options

● Tight constant-voltage and constant current

regulation across line and load range

● SmartDefender? smart hiccup technology helps

to address issues of soft shorts in cables and

connectors by effectively reducing the average output

power at fault conditions without latch

● Optional on-chip internal over-temperature protection

● No audible noise over entire operating range

● 10-lead SOIC batwing package
