Texas Instruments LM5122 | Demoboard PMP10503
High-Efficiency Single-Phase Synchronous Boost Conv for Automotive Infotainment Reference Design
Overview
| Topology | Boost Converter |
| Input voltage | 7-36 V |
| Output 1 | 48 V / 1 A |
| IC revision | 1 |
Description
PMP10503 is a Single-Phase Synchronous Boost Converter using the LM5122 controller IC. The design accepts an input voltage of 7Vin to 36Vin (14Vin Nominal) and provides an output of 48Vout capable of supplying 1A of continuous current to the load. The design was built on the PMP7896 RevB PCB, which was modified to the PMP10503 design configuration and requirements.
Features
- High efficiency design
- High power density: 48W/15.2 Sq. inches
- Synchronizable to external clock
- Cycle-by-Cycle Current limit with programmable hiccup mode overload protection
- Bypass mode capable when Vin > Vout
- Low component temperature rise at nominal power operation
