Overview

15W 5 V USB adapter reference design board using Quasi-Resonant PWM IC ICE2QS03G with CoolMOS™ IPS65R1K5CE

15W Adapter Reference Board

This is the 15W 5 V USB adapter reference design board using Quasi-Resonant PWM IC ICE2QS03G (DSO-8) with CoolMOS™ IPS65R1K5CE (IPAK SL) and secondary side synchronous rectification IC IR1161 (5-Pin SOT-23) with OptiMOS™ BSZ100N06LS3 G (S3O8, 3x3 mm style SuperSO8). The reference USB adapter board is specially designed in a very small form factor, high efficiency, low standby power, various modes of protections for a high reliable system and it pass conductive EMI, ESD and Lightning surge test. This board can be used for production by customers after final verification with minor changes.

Summary of Features

Quasi-Resonant flyback with state-of-art CoolMOS – high efficiency and low EMI noise
Active burst mode with high voltage startup cell very low standby power consumption
Secondary side synchronize rectification controller with stat-of-art OptiMOS - further improve the efficiency
Various modes of protections and rugged CoolMOS – high reliable system
