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 100V. The single control input is patible with TTL signal levels and a single external resistor programs the switching transition dead-time through tightly matched turn-on delay...
