Texas Instruments LMR51420 | Demoboard LMR51420EVM
LMR51420 evaluation module 4.5-V to 36-V, 2-A synchronous step-down converter
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-36 V |
| Output 1 | 0.6 V / 2 A |
Description
The UCC14240-Q1 evaluation module (EVM) is a DC/DC converter module, providing 1.5-W of 3 kVRMS, isolated power in a low-profile, 3.5-mm, wide body SOIC integrated package. The UCC12040EVM-052 EVM can operate from 21 V < VIN < 27 V and is configured for dual outputs of VDD = +15 V and VEE = -5 V, demonstrating typical bias supply voltages required by IGBT and SiC gate driver ICs used in high-voltage, industrial and automotive inverters, battery management systems, charging stations and various isolated equipment applications.
Features
- 4.5-V to 36-V input voltage range
- Default 5-V output
- Up to 2-A output current
- 500-kHz switching frequency
- Hiccup mode short current protection
- Internal compensation
Typical applications
- appliances
- General purpose wide VIN power supplies
- Building automation, Motor drives
