Onsemi NCP1340/NCP43080/NCP4371 | Demoboard DN05099/D

Description

This design note describes a 36 watt, Type C interface PD3.0/QC3.0, universal AC input, constant voltage power supply intended for smart phone, PAD and NB adaptor supporting PD3.0 and QC3.0 protocol, where isolation from the AC mains is required, and low cost, high efficiency, and low standby power are essential.

Features

1. Universal AC input range (90 – 264 Vac)
2. Very low standby (no load) power consumption
3. Very low ripple and noise
4. Inherent SCP and OCP protection
5. High frequency operation
6. High power density (1.2 W/cm3)
7. Quasi-Resonant current mode control with Valley Switching
8. Quasi-Resonant current mode control with Valley Switching
9. Valley lockout avoids audible noise at valley jumping operation
10. Support TYPE C interface PD3.0 and QC3.0 Class A&B specification
11. Adaptive Output OVP and UVP
12. Output CC @QC2.0 and QC3.0 mode
13. Two PCB boards back-to-back assembled
14. Board size: 51mmx28mmx21mm

Typical applications

• Smart phone, PAD and NB adapter supporting PD3.0 and QC3.0 protocol
