15W 5V charger reference design using 700V CoolMOS™P7

EVAL_15W_5V_FLYB_P7

Overview

This is a 15W 5.0V/3.0A USB adapter reference design using an AC-DC quasi-resonant PWM controller IC (ICE2QS03G), an IPAK packaged 700V CoolMOS™ P7 SJ MOSFET (IPS70R1K4P7S), an OptiMOS™ 60V low voltage power MOSFET ( BSC067N06LS3G) and high-speed switching diodes (BAS21-03W), shaped like slim plugs with various protection modes.

Feature description

Output overshoot/negative pulse during dynamic load: ±2%
Maximum input power (peak power) over the full input range: Input power < ±5%
Efficiency: >80% at average efficiency in active mode (25%, 50%, 75% and 100% load)
Standby: < 50mW at no load

Summary of advantages

Shaped like a slim plug, achieving 15W rated power
Introducing IPAK packaging into ultra-thin adapter system solutions

target application

charger
