3 Description
The LM5109A 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 highside driver is capable of working with rail voltages up to 90V. The outputs are independently controlled with TTL patible input thresholds....
