Small Automotive High Input Voltage 3W Isolated Flyback: 50V…600Vin to 15V@200mA Reference Design

Description

This simple isolated flyback converts 50V…600Vin to 15V@200mA. The LM5021-1 controller is suitable for green mode converters due to pulse skip mode. Since the input maximum voltage is 600V: the pulse skip mode improves the efficiency due to the reduction of the switching losses.

Features
  • Wide Vin capability (50 to 600V DC)Duty cycle restriction to 80%84% full load efficiencyLess than 70mW consumed at no loadPulse skipping mode resulting in reduction of switching lossesLow component count (as there is no need for external slope compensation) with LM5021-1
Applications
  • Flow transmitter
  • Pressure transmitter
  • Temperature transmitter
  • Process Analytics (pH
  • Gas
  • Concentration
  • Force & Humidity)
  • Level transmitter
  • Position sensor
