Product Overview

The LT8631HFE#PBF is a synchronous micro-power step down (buck) regulator with adjustable output in 20 pin TSSOP package. This current mode PWM DC to DC converter has internal synchronous switches. Low ripple burst mode operation enables high efficiency operation down to very low output currents while keeping output ripple below 10mVP-P. Resistor programmable frequency range from 100KHz to 1MHz and synchronization capability enable optimization between efficiency and external component size. The soft start feature controls ramp rate of output voltage by eliminating input current surge during start-up and also provides output tracking. A power good flag indicates when output voltage is within ±7.5% of regulated output. Undervoltage lockout can be programmed using the EN/UV pin and shutdown mode reduces total quiescent current to less than 5µA.
  • Adjustable output voltage range from 0.8V to 60V
  • Output current of 1A
  • Ultra wide input voltage range from 3V to 100V
  • Low dropout and 99% maximum duty cycle
  • Peak current mode control
  • Tolerates pin open/short faults
  • Short circuit protection
  • Low shutdown current of 5µA
  • Synchronization input
  • Operating junction temperature range from -40°C to 150°C
