Texas Instruments LMQ644A2-Q1 | Demoboard LMQ644A2QEVM-D2100
LMQ644A2-Q1 dual output synchronous buck converter evaluation module
Overview
| Topology | Buck Converter |
| Input voltage | 6-36 V |
| Output 1 | 3.3 V / 6 A |
| Output 2 | 5 V / 6 A |
| IC revision | A |
Description
The LMQ644A2QEVM-D2100 evaluation module (EVM) evaluates the features and performance of the LMQ644A2-Q1, dual buck DC/DC converter with integrated power MOSFETs. The EVM provides dual 6 A outputs. The output voltage can be individually programmed to a fixed 3.3 V and 5 V or adjustable using external feedback resistors. Each channel can be enabled and or disabled by a jumper selection.
Features
- 6 V to 36 V input voltage range
- 5 V and 3.3 V output voltages
- Rated for 6 A per channel
- Ultra low IQ
- Dual-random spread spectum
Typical applications
- Automotive infotainment and cluster: head unit, media hub, USB charge, display
- Automotive ADAS and body electronics, Automotive infotainment and cluster: head unit, media hub, USB charge, display
