Beschreibung
High Density 72W Battery Powered Synchronous Boost Reference DesignPMP11422 is a synchronous boost power supply using the LM5121 controllers. The design accepts an input voltage of 5Vin to 8.6Vin, and boosts a 12Vout rail capable of sourcing 6A continuous current. The LM5121 integrates an input disconnection switch feature which allows boost short circuit protection, the device turns off the switch when a short circuit event occurs.
