Product Overview

The LTC3622HDE-2#PBF is an adjustable output dual synchronous step down regulator in 14 pin DFN package. This monolithic switching regulator uses constant frequency peak current mode architecture. It has ultralow quiescent current and high efficiency over a wide output voltage range. A user selectable mode input is provided to allow user to trade off ripple noise for light load efficiency. The burst mode operation provides highest efficiency at light loads while pulse skipping mode provides lowest ripple noise. The current mode operation yields excellent line and load transient response. The LTC3622 can be synchronized to an external clock.
  • Constant frequency of 2.25MHz with external frequency synchronization
  • Adjustable output voltage range from 0.6V to 17V
  • Dual step down outputs with 1A output current per channel
  • Wide input voltage range from 2.7V to 17V
  • No load quiescent current of 5µA (both channels enabled) and less than 4µA (one channel enabled)
  • High efficiency of 95% and low dropout operation (100% duty cycle)
  • ±1% output voltage accuracy
  • Phase shift programmable with external clock
  • Selectable current limit, internal compensation and soft start
  • Operating junction temperature range from -40°C to 150°C
