AC Voltage Zero Cross Detection IC

Overview

TopologyFlyback Converter
Input voltage90-264 V
Output 15.25 V
IC revision001

Description

This IC outputs the AC voltage zero cross timing detection with high accuracy. By eliminating the need for photocoupler and external components required in conventional applications, it is possible to reduce the number of parts drastically and realize compact and highly reliable power supply applications. In addition, this IC can reduce standby power largely in comparison with an existing photocoupler control.

Features

  • VCC Input Power Supply Voltage Range: -0.3 V to +29.0 V
  • VH_AC1 and VH_AC2 Pins Operation Voltage: 600 V (Max)
  • Circuit Current at Standby: 50 μA (Typ)
  • Circuit Current at Operation: 160 μA (Typ)
  • Operating Temperature Range: -40 °C to +105 °C
