The LM5109 smd ic is a low cost 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 100V.
The outputs are independently controlled with TTL compatible input thresholds. A robust level shifter technology operates at high speed while consuming low power and providing clean level transitions from the control input logic to the high side gate driver.
