LTC3630AIMSE#WTRPBF

LTC3630AIMSE#WTRPBF is a high efficiency, synchronous step-down DC/DC converter with internal high side and synchronous power switches that draw only 12μA typical DC supply current while maintaining a regulated output voltage at no load. This can supply up to 500mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and reducing output ripple and component size. This combination of Burst Mode® operation, integrated power switches, low quiescent current, and programmable peak current limit provides high efficiency over a broad range of load currents. With its wide input range of 4V to 76V, this is a robust converter suited for regulating a wide variety of power sources. A feedback comparator output enables multiple to be paralleled in higher current applications. Application includes industrial control supplies, medical devices, portable instruments, automotive, avionics.
