LTC3412EFE#PBF

LTC3412 is a high efficiency monolithic synchronous, step-down DC/DC converter utilizing a constant frequency, current mode architecture. It operates from an input voltage range of 2.625V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering upto 2.5A of output current. The internal synchronous power switch with 85Mohm on-resistance increases efficiency and eliminates the need for An external schottky diode. Switching frequency is set by an external resistor or can be synchronized to an external clock. 100% duty cycle provides low dropout operation extending battery life in portable systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of loads and output capacitors. It is used in application such as portable instruments, battery-powered equipment, notebook computers, distributed power systems, cellular telephones, digital cameras etc.
