Produktbeschreibung
LTC3526BEDC#TRMPBF 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 an 850mV start-up voltage and operation down to 500mV once started. A switching frequency of 1MHz minimizes the solution footprint by allowing the use of tiny, low-profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing the external parts count. The LTC3526 features automatic Burst Mode operation at light load conditions, while 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 low shutdown current of under 1µA and thermal shutdown. Applications include medical instruments, flash-based MP3 players, noise-cancelling headphones, wireless mice, and Bluetooth headsets.
- 1.6V to 5.25V VOUT range, output disconnect, up to 94% efficiency
