Product Overview

The LTC3603EMSE#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 4.5 to 15V and provides an adjustable regulated output voltage from 0.6 to 14.5V while delivering up to 2.5A of output current. The internal synchronous power switch with 45mR on-resistance increases efficiency and eliminates the need for an external Schottky diode. The switching frequency can either be set by an external resistor or 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 LTC3603 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 the highest efficiency at light loads.
  • Adjustable Burst Mode® clamp
  • Synchronizable to external clock
  • Power good output voltage monitor
  • Over-temperature protection
  • Overvoltage protection
  • 99% Maximum duty cycle
  • 75µA Low quiescent current
