LM5109B Datasheet (National Semiconductor) - High Voltage 1A Peak Half Bridge Gate Driver

LM5109B, High Voltage 1A Peak Half Bridge Gate Driver

The LM5109B is a cost effective, high voltage gate driver designed to drive both the high-side and the low-side N-Channel MOSFETs in a synchronous buck or a half bridge configuration.

The floating high-side driver is capable of working with rail voltages up to 90V.

The outputs are independently cont
