General Description
The LTC®3612 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.
