Overview
| Topology | Buck Converter |
| Input voltage | 20-40 V |
| Output 1 | 5 V / 10 A |
Description
The UC1843B-SP EVM uses the UC1843B-SP, INA901-SP, LM139AQML-SP, and UC1901-SP to create an isolated feedback flyback with current sensing and overcurrent flags. The UC1843B-SP is used to switch the low side MOSFET of the flyback converter and provides voltage and current to the output. The system uses the UC1843B-SP to provide 5-V and 10-A outputs. These outputs are not dependent on the UC1843B-SP itself, and can be increased or decreased depending on the design. The INA901-SP senses the input current which is then provided to the LM139AQML-SP to create an overcurrent flag. In a full system, this flag could be used to shutdown the UC1843B-SP and turn off the converter.
Features
- Pulse-by-pulse current limiting using UC1843B-SP
- PWM control using UC1843B-SP
- Current sensing using INA901-SP
- Overcurrent comparison using LM139AQML-SP
Typical applications
- Radiation hardened applications
- Space satellite isolated power supplies, Space satellite payloads
