LTC3639MPMSE#PBF

LTC3639 is a high efficiency step-down DC/DC regulator with internal high side and synchronous power switches that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. This device’s 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. Additionally, this device includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. It is widely used in application such as industrial control supplies, medical devices, distributed power systems, portable instruments, battery-operated devices, automotive, avionics etc.

• Wide operating input voltage range is 4V to 150V, synchronous operation for highest efficiency
