LTC3646IDE#PBF, Импульсный понижающий DC-DC стабилизатор, регулируемый, 4В-40В (Vin), 2В-30В, 1А, DFN-14
The LTC3646IDE#PBF is a high-efficiency step-down DC-to-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. The LTC3646 can supply up to 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 LTC3646 has a wide 4 to 40V input range and its patented controlled on-time architecture and 0.6V reference voltage allow for large step-down ratios without the risk of output overvoltage. The frequency may be set between 200kHz and 3MHz with a program resistor or synchronized to an external clock. The internal soft-start, short-circuit protection and voltage rating make the LTC3646 a robust part ideal for high voltage applications.
