Texas Instruments LMR38020-Q1 | Demoboard LMR38020QEVM
LMR38020-Q1 evaluation module SIMPLE SWITCHER® power converter 80-V, 2-A, synchronous buck, 40-µA IQ
Overview
| Topology | Buck Converter |
| Input voltage | 6-80 V |
| Output 1 | 5 V / 2 A |
Description
The LM38020QEVM evaluation module (EVM) uses the LMR38020S-Q1, a 80-V DC/DC buck regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 6 V to 80 V to provide a regulated 5-V output at 400-kHz switching frequency. The output voltage has better than 1.5% setpoint accuracy and is adjustable using an external resistor divider. The LMR38020QEVM is qualified for the LMR38020-Q1 as well as the LMR38020 buck converter.
Features
- 4.5-V to 80-V input voltage range
- Accurate 5-V output
- Up to 2-A output current
- Switching frequency 400 kHz
- Spread spectrum to reduce EMI
Typical applications
- Industrial transport, Factory automation and control
- Wireless infrastructure and networking
