● Supports Rapid Charge adapters applications of

typical 25W and other power profiles

● Supports constant-voltage (CV) and constant-current

(CC) regulation in fine steps using secondary-side

regulation (SSR) control

● Proprietary constant-frequency switching with quasiresonant

(QR) operation achieves best size, effiiciency

and common mode noise

● Adaptive QR mode and optional continuous

conduction mode (CCM) operation at low line voltage

● Adaptive multi-mode control (MMC) using PWM/

PFM/Burst modes based on input voltage and output

voltage/current improves efficiency and eliminates

audible noise

● Built-in single-point fault protections against AC line

voltage brown-out, output short-circuit, output overvoltage,

and optocoupler failure

● User programable internal OTP threshold for various

thermal requirement

● < 20mW no load standby power with ample margin at

230VAC when output USB cable is detached.

● 8-lead SOIC package
