Product Overview

The LTC3418EUHF#PBF is a high-efficiency monolithic synchronous step-down DC-to-DC Converter utilizing a constant frequency and current-mode architecture. It operates from an input voltage range of 2.25 to 5.5V and provides a regulated output voltage from 0.8 to 5V while delivering up to 8A of output current. 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. The LTC3418 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.
  • Synchronizable switching frequency
  • Power good output voltage monitor
  • Over-temperature protection
  • Tracking input to provide easy supply sequencing
  • Up to 95% high efficiency
  • 380µA Quiescent current
