Description

This reference design highlights an ultra-low standby isolated AC/DC auxiliary power stage followed by converters and linear regulators, a comparator-based control pilot interface to meet the SAE J1772 standard, an efficient relay and contactor drive and isolated line voltage sensing across the relay and contactor. Electric vehicle service equipment (EVSE) facilitates power delivery to electric vehicles safely from the grid. An EVSE control system consists of an auxiliary power stage, an off-board AC/DC high power stage (only in DC charging stations), energy metering unit, AC and DC residual current detector, an isolation monitor unit, relays and contactors with drive, two-way communication over single wire, service and user interfaces.

Features

Less than 10-mW No-Load Power Capability
Optocoupled Feedback for CV, and Primary-Side Regulation (PSR) for CC
Enables ±1% Voltage Regulation and ±5% Current Regulation Across Line and Load
700-V Startup Switch - 100-kHz Maximum Switching Frequency Enables High-Power-Density Charger Designs
Resonant-Ring Valley-Switching Operation for Highest Overall Efficiency
Frequency Dithering to Ease EMI Compliance
Clamped Gate-Drive Output for MOSFET
Overvoltage, Low-Line, and Overcurrent Protection Functions - SOIC-7 Package

Typical applications

USB-Compliant Adapters and Chargers for Consumer Electronics / Standby Supply for TV and Desktop / White Goods
