The LM5109 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 …
