LM5105 Datasheet (National Semiconductor) - 100V Half Bridge Gate Driver

LM5105, 100V Half Bridge Gate Driver

The LM5105 is a high voltage gate driver designed to drive both the high side and low side N *Channel MOSFETs in a synchronous buck or half bridge configuration.

The floating high-side driver is capable of working with rail voltages up to 100V.

The single control input is compatible with TTL
