LM5105 Description

The LM5105 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 is capable of working with rail voltages up to 100 V. The single control input is patible with TTL signal levels and a single external resistor programs the switching transition dead time through tightly matched turnon delay...
