LTC3418EUHF#TRPBF

LTC3418 is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant frequency, current mode architecture. The internal synchronous power switch 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. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of loads and output capacitors. This device can be configured for either Burst Mode operation or forced continuous operation. Forced continuous operation reduces noise and RF interference while Burst Mode operation provides high efficiency by reducing gate charge losses at light loads. It is used in application such as microprocessor, DSP and memory supplies, distributed 2.5V, 3.3V and 5V power systems, automotive applications, point of load regulation, notebook computers etc.
