LTC3526LBEDC-2#TRMPBF Datasheet PDF - Linear Technology

●The LTC3526LBEDC-2#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 a 680mV start-up voltage and operation down to 500mV once started. A switching frequency of 2MHz 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 LTC3526LB-2 features fixed frequency operation for low noise applications. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal shutdown.
