Texas Instruments LM5122-Q1 | Demoboard PMP11479
98% Efficient 30W Synchronous Automotive Pre-Boost Reference Design
Overview
| Topology | Boost Converter |
| Input voltage | 6-16 V |
| Output 1 | 12 V / 2.5 A |
| IC revision | A |
Description
98% Efficient 30W Synchronous Automotive Pre-Boost Reference Design. PMP11479 is a synchronous boost power supply using the LM5122-Q1 controllers. The design accepts an input voltage of 6Vin to 16Vin, and boosts a 12Vout rail capable of sourcing 2.5A continuous current. The LM5122-Q1 has an internal current source to keep the high side FET to run at 100% duty cycle which allows a bypass operation when the input voltage is greater than the configured output voltage.
Features
- 6V to 16V in, output 12V@ 2.5A
- Achieving efficiency of 98% at 12Vin
- High density design
- Solution size: 36mm x 23mm
- Overvoltage and overcurrent protection
