The LM5109B from Texas Instruments is a cost-effective, high-voltage gate driver suitable for synchronous buck or half-bridge configurations. It is designed to drive both the high-side and low-side N-channel MOSFETs.
Key electrical specifications include a 1A peak output current (sink and source), fast propagation times of 30 ns typical, and excellent propagation delay matching of 2 ns typical. The device drives a 1000 pF load with 15 ns rise and fall times. It features independent TTL-compatible inputs and supply rail under-voltage lockout for both low-side and high-side power rails.
The LM5109B supports a bootstrap supply voltage up to 90V and operates with an input supply voltage between 8V and 14V. The typical undervoltage lockout is 8V. The device is available in SOIC-8 and WSON-8 (4 mm x 4 mm) packages, both supporting surface mount.
Typical applications include current-fed push-pull converters, half and full bridge power converters, solid-state motor drives, and two-switch forward power converters.
