High Voltage Input (184Vac…707Vac) to 12V@1A, 3.3V@100mA Non-isolated Flyback Reference Design

Overview

TopologyBuck Converter
Input voltage12 V
Output 13.3 V / 0.1 A
IC revisionC

Description

The UCC28720 is a quasi resonant controller and is specialized to drive high voltage BJTs. When the drain voltage is higher than 1KV, BJTs are the best choice for low to mid power flyback converters. In this case two voltages are supplied: 12V@1A and 3.3V@100mA.

Features

remark: bom and schematic is added.

Over 84% efficiency at full loadOver 70% efficiency at 10% loadProvides 12V and 3.3V outputsWorks continuously up to 440Vac input and survives 1KVpeak surge
