LTC3646EMSE#PBF

LTC3646 is a high efficiency, step-down DC/DC converter with internal high side and synchronous power FETs. It draws only 140µA typical DC supply current in burst mode operation at no load while maintaining output voltage regulation. This device can supply upto a 1A load, and its combination of burst mode operation, integrated power switches and low quiescent current provides high efficiency over a broad range of load currents. Alternatively, it can be used in forced continuous mode for ripple sensitive applications. The internal soft-start, short-circuit protection and voltage rating make the device a robust part ideal for high voltage applications. It is widely used in application such as point of load power supplies, intermediate bus power, automotive applications etc.
