LTC3526LBEDC-2#TRMPBF

LTC3526LB-2 is a synchronous, fixed frequency step-up DC/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. This device 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. It is used in application such as medical instruments, noise cancelling headphones, wireless mice, Bluetooth headsets etc.
