● Zero standby power consumption with low system cost

(< 5mW at 230VAC when output USB cable is detached

in a typical 25W USB PD travel adapter) - iW9860

● Lowest BOM cost with < 20mW no-load power

consumption by removing the need for external startup

DFET - iW9861

● Supports single-layer PCB design to reduce total

system cost

● Supports Rapid Charge adapters applications of

15W-63W and other power profiles

● Uses Renesas’ patented switching modes [adaptive

quasi-resonant (QR) operation and adaptive multi-mode

control (MMC)] and continuous conduction mode (CCM)

x Improves efficiency and eliminate audible noise

x Enables optimization for size, efficiency and EMI

performance

● Supports voltage sensing with dual polarity of VVCC

auxiliary winding for improving EMI and simplifying

transformer design

● Intelligent gate drive control to minimize driving loop

and eliminate high voltage capacitor

● Max switching frequency range - 70kHz to 130kHz

(by product option - see Section 7)

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

(CC) regulation in fine steps using secondary-side

regulation (SSR) control

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

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

output over-voltage, and optocoupler failure

● User adjustable internal OTP threshold for various

thermal requirements

● 6-lead SOT-23 package supports compact power supply design
