LTC3612EFE#PBF Description
The LTC3612EFE#PBF is a low quiescent current monolithic synchronous buck regulator using a current mode, constant frequency architecture. The no-load DC supply current in sleep mode is only 70µA while maintaining the output voltage (Burst Mode operation) at no load, dropping to zero current in shutdown. The 2.25V to 5.5V input supply voltage range makes the LTC3612EFE#PBF ideally suited for single Li-Ion and fixed low-voltage input applications. 100% duty cycle capability provides low dropout operation, extending the operating time in battery-powered systems.
