Microchip MCP19125 | Demoboard EV61C15A

MCP19125 28V to 48V Isolated Flyback DC-DC Evaluation

Overview

TopologyFlyback Converter
Input voltage28-48 V
IC revision1

Description

The MCP19124/5 are highly integrated, mixed-signal, low-side synchronous controllers that operate from 4.5Vto 42V. The MCP19124/5 family features individual analog PWM control loops for both current regulation orvoltage regulation. These features, along with an integrated microcontroller core, make these devices ideal forbattery charging applications, LED lighting systems and any other low-side switch PWM applications.

Features

  • Input Voltage: 20.0V to 36.0V
  • Programmable Output Voltage Range: 40.0V to 55.0V
  • Programmable Output Current Limit: 0A to 2.0A
  • Programmable Over-Voltage Limit: 40.0V to 65.0V
  • Programmable Over-Temperature Limit: 40.0°C to 85.0°C
  • Programmable Soft-Start of 120 ms to 2200 ms
  • I2C Interface for Programming and Monitoring the board, providing feedback on:– Output Voltage– Output Current– Input Voltage– Input Current– Board Temperature
  • Isolated Output Voltage
  • Test Points and Headers for All Available Outputs and Input
