LTC3612 synchronous buck regulator
LTC3612 is a low quiescent current monolithic synchronous buck regulator . The LTC3612 use a current mode, constant frequency architecture .
The LTC3612 synchronous buck regulator operates from 2.25V to 5.5V input supply voltage range.
The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. The maximum output current of the LTC3612 synchronous buck regulator is around 3 Amps .
Other features offered by the LTC3612 manufactured by Linear Technology are : Low Output Ripple Burst Mode® Operation: IQ = 70μA , ±1% Output Voltage Accuracy , Output Voltage Down to 0.6V , High Efficiency: Up to 95% , Low Dropout , Shutdown Current: ≤1μA , Adjustable Switching Frequency: Up to 4MHz , Optional Active Voltage Positioning (AVP) with Internal Compensation , Selectable Pulse-Skipping/Forced Continuous/Burst Mode Operation with Adjustable Burst Clamp , Programmable Soft-Start and other .
Few external components required and high current capability in a small package make it ideal for portable applications .
