Overview
The LM5109B device is a cost-effective high-voltage gate driver designed to drive high-side and low-side N-channel MOSFETs in synchronous buck or half-bridge configurations. The floating high-side driver can operate with supply rail voltages up to 90V. The outputs are independently controlled via cost-effective TTL- and CMOS-compatible input thresholds. A robust level-shifting technique combines high operating speed and low power consumption and provides clean level shifting from the control input logic to the high-side gate driver. The device provides undervoltage lockout on both the low-side and high-side supply rails. The device is available in an 8-pin SOIC and a thermally enhanced 8-pin WSON package.
Applications
- Current feedback push-pull converters
