Product Overview

The LTC3621HMS8E-23.3#PBF is a high efficiency synchronous step down (buck) regulator with fixed output in 8 pin MSOP package. This monolithic regulator uses constant frequency peak current mode architecture. It has ultralow quiescent current and high efficiencies over wide output voltage range. The user selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency. The burst mode operation provides highest efficiency at light loads and pulse skipping mode provides lowest voltage ripple. The MODE pin allows user to sync the switching frequency to an external clock. The current mode operation of LTC3621 provides excellent line and load transient response.
  • Constant frequency of 2.25MHz
  • Fixed output voltage of 3.3V
  • Rated output current of 1A
  • Wide input voltage range from 2.7V to 17V
  • Maximum efficiency of 95% and output voltage accuracy of ±1%
  • Low quiescent current of less than 3.5µA, zero current shutdown
  • Full dropout operation with low quiescent current and synchronized to external clock
  • Pulse skipping, forced continuous and burst mode of operation
  • Internal compensation, soft start and overtemperature protection
  • Operating junction temperature range from -40°C to 150°C
