Small Automotive High Input Voltage 3-W Isolated Flyback: 50 V…600 Vin to 15 V @ 200 mA Re
Texas Instruments
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
- Fuel cell control unit (FCCU)
- Traction inverter-low voltage
- Bidirectional 400-V & 800-V to LV
