Texas Instruments LM5109AMAX/NOPB

Description
The LM5109A 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 can work with rail voltages up to 90V. The outputs are independently controlled with TTL compatible input thresholds. The level-shift 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. Under-voltage lockout is provided on both the low-side and high-side power rails. The device is available in SOIC and WSON packages.
