Product Description
LTC7801EUFD Integrated Circuit Chip 150V Synchronous Step-Down DC/DC Controller For Humanoid Robots
LTC7801EUFD is an industrial high-performance all N-channel synchronous step-down DC-DC controller, optimized for high-power power supply systems of 24V/48V lithium battery powered humanoid robots.
LTC7801EUFD supports ultra-wide input voltage from 4V to 140V with 150V absolute maximum rating, which eliminates extra surge suppression components and directly withstands voltage spikes caused by servo startup and battery hot swapping.
