Product Overview

The LTC3413EFE#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 equal to (0.5)VREF while sourcing or sinking up to 3A of output current. An internal voltage divider reduces component count and eliminates the need for external resistors by dividing the reference voltage in half. The internal synchronous power switch with 85mR on-resistance increases efficiency and eliminates the need for an external Schottky diode. Switching frequency up to 2MHz are set by an external resistor. Forced-continuous operation in the LTC3413 reduces noise and RF interference. Fault protection is provided by an overcurrent comparator that limits output current during both sourcing and sinking operations. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
  • Symmetrical source and sink output current limit
  • No Schottky diode required
  • Power good output voltage monitor
  • Over-temperature protection
  • Up to 90% high efficiency
  • ±1% Output voltage accuracy
