LTC3526BEDC#TRMPBF Datasheet PDF - Linear Technology

●The LTC3526BEDC#TRMPBF is a synchronous fixed frequency step-up DC-to-DC Converter with output disconnect. Battery life in single AA/AAA powered products is extended further with an 850mV start-up voltage and operation down to 500mV once started. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current-mode PWM design is internally compensated, reducing external parts count. The LTC3526B features continuous switching at light loads. Anti-ringing control circuitry also reduces EMI concerns by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal shutdown.
