Product Overview

The LT8331IMSE#PBF is a current mode boost/SEPIC/flyback/inverting DC to DC converter with unique single feedback pin architecture in 16 pin MSOP package. Burst mode operation consumes as low as 6µA quiescent current to maintain high efficiency at very low output currents while keeping typical output ripple below 20mV. The internally compensated current mode architecture results in stable operation over a wide range of I/O voltages and programmable switching frequencies. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst and pulse skipping modes of operation. A BIAS pin can accept second input to supply INTVCC regulator for increased efficiency. The LT8331 also includes frequency foldback and programmable soft start for controlling inductor current during start-up.
  • Power switch output is rated for 0.5A, 140V
  • Wide input voltage range from 4.5V to 100V
  • Ultralow quiescent current and low ripple
  • Positive or negative output voltage programming with single feedback pin
  • Programmable switching frequency from 100KHz to 500KHz
  • Synchronized to an external clock
  • BIAS pin for higher efficiency
  • Programmable undervoltage lockout (UVLO)
  • Operating junction temperature range from -40°C to 125°C
