Overview
| Topology | Buck Converter |
| Input voltage | 3-36 V |
| Output 1 | 5 V / 2 A |
| IC revision | A |
Description
The LMR43620RQ5EVM-400 evaluation module (EVM) helps evaluate the operation and performance of the LMR43620-Q1 wide-input buck regulator. The LMR43620-Q1 is an easy-to-use synchronous step-down DC/DC converter capable of driving up to 2 A of load current from an input voltage of up to 36 V. The LMR43620-Q1 has ultra-low operating quiescent current and high efficiency at light loads. The LMR43620-Q1 comes in small 2x2 mm HotRod™ package providing a very small, low-EMI solution size.
Features
- Wide input voltage range of 3 V to 36 V
- 5 V fixed output votlage by default
- Output current up to 2 A
- 400 kHz default switching frequency (jumper included for frequency selection)Fully assembled, tested and proven PCB layout with small solution footprint
Typical applications
