98% Efficient 30W Synchronous Automotive Pre-Boost Reference Design
Description
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@ 2.5AAchieving efficiency of 98% at 12VinHigh density designSolution size: 36mm x 23mmOvervoltage and overcurrent protection
