Product Overview

The LTC3872EDDB#PBF is a constant frequency current-mode boost DC/DC Controller drives an N-channel power MOSFET and requires very few external components. The No RSENSE architecture eliminates the need for a sense resistor, improves efficiency and saves board space. It provides excellent AC and DC load and line regulation with ±1.5% output voltage accuracy. It incorporates an under voltage lockout feature that shuts down the device when the input voltage falls below 2.3V. High switching frequency of 550kHz allows the use of a small inductor.
  • No current sense resistor required
  • VOUT up to 60V
  • Internal soft-start and optional external soft-start
  • Adjustable current limit
  • Pulse skipping at light load
  • Current mode operation for excellent line and load transient response
