Product Overview

The LT8495HFE#PBF is an adjustable frequency current mode SEPIC/boost/flyback switching regulator in 20 pin TSSOP package. The quiescent current is less than 9µA when operating and is equivalent to 0.3µA when SWEN, WDE, complementary RSTIN pins are low. The low ripple burst mode operation maintains high efficiency at low output current while keeping output ripple below 10mV. Dual supply pins (VIN and BIAS) improves efficiency and allow regulator to automatically operate from most efficient supply. Input supply voltage is up to 60V for SEPIC topologies and up to 32V (with ride through up to 60V) for boost and flyback topologies. After start-up, battery life is extended so that LT8495 can draw current from its output (BIAS) even when VIN voltage drops below 2.5V. The reset and watchdog timeout periods are independently adjustable using external capacitors. This monolithic switching regulator has integrated frequency foldback and soft start functions.
  • Integrated power switch output is rated for 2A and 70V
  • Wide input voltage range of 1V to 60V (2.5V to 32V for start-up)
  • Programmable switching frequency range from 250KHz to 1.5MHz
  • Soft start programmable with one capacitor
  • Programmable watchdog timer can operate when VIN supply is removed
  • Programmable power-on reset timer (POR)
  • Dual supply pins reduces minimum supply voltage to 1V after start-up to extend battery life
  • UVLO programmable on SWEN and complementary RSTIN pins
  • Operating junction temperature range from -40°C to 150°C
  • FMEA fault tolerant
