Onsemi NCP1340/NCP4306/WT6632F | Demoboard DN05102/D
45W TYPE-C PD3.0 / QC3.0 Power Adapter Solution with WT6632F
Overview
| Topology | Flyback Converter |
| Input voltage | 90-264 V |
| Output 1 | 20 V / 2.25 A |
Description
This design note describes a 45 W, Type Cinterface PD2.0, universal AC input, constant voltage power supply intended for smart phone, PAD and NB adaptor supporting PD3.0 or QC3.0 protocol, where isolation from the AC mains is required, and low cost, high efficiency, and low standby power are essential.
Features
Universal AC input range (90 – 264 Vac)Very low standby (5 V & 230 Vac) power consumption with no cable plug inVery low ripple and noiseInherent SCP and OCP protectionHigh operation frequency up to 150kHzHigh power density (1.15 W/cm3)Quick switching off FET while unplugging cable and switching on FET at Vbus dropping to 5 V while plugging cable againQuasi-Resonant current mode control with Valley SwitchingValley lockout avoids audible noise at valley jumping operationSupport TYPE-C PD3.0 & QC3.0 protocolAdaptive Output OVP and UVPOpen loop protectionBoard size: 57mmx36mmx19mm
Typical applications
- TYPE-C PD Power Adapter
