LTC3388EDD-1#PBF

降压开关稳压器, 固定, 2.7V-20V输入, 2.5V和50mA输出, DFN-10

The is a high efficiency step-down DC/DC Converter with internal high side and synchronous power switches that draw only 720nA typical DC supply current at no load while maintaining output voltage regulation. Capable of supplying 50mA of load current, it also incorporate an accurate undervoltage lockout UVLO feature to disable the converter and maintain a low quiescent current state when the input voltage falls below 2.3V. In regulation, it enters a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation. An additional standby mode disables buck switching while the output is in regulation for short duration loads requiring low ripple.
