NCP1361: Universal AC Input, 5V3A Output, 15 Watt adapter

Overview

TopologyFlyback Converter
Input voltage90-264 V
Output 15.5 V / 3 A

Description

This design note describes a 15 watt, universal AC input, isolated Quasi-Resonant flyback converter for smart phone, tablet charger and smart socket power supply etc.The featured power supply is a primary side constant current and secondary constant voltage regulation utilizing ON semiconductor’s new NCP1361 current mode controller which is in TSOP6 package. This Design Note provides the complete circuit schematic details, layout, test data and BOM for 5.1 volts, 3 amps power supply.

Features

 Primary Side CC Regulation and Secondary CV Regulation Quasi-Resonant current mode control with Valley Switching Valley lockout avoids audible noise at valley jumping operation External 10M startup resistor Built in 4ms soft start 80kHz maximum clamp frequency operation Adjustable voltage control loop compensation Wide Operation VCC range (up to 30 V) Cycle by cycle current limit Support external 2200Uf startup Built in Vcc OVP (typical 26v) Built in output UVP in CC mode (3V+/-6.7%) Output OCP, SCP, OVP and controller OTP function CS pin open and short protection Vs pin open and short protection Meet COC V5 Tier 2 100pF Y capacitor “Travel Adapter” (TA) form factor Size: 43.5mm x 35mm x 15mm

Typical applications

  • Mobile, tablet Charger,adapter
