Product Overview

The LT3688EFE#PBF is a dual monolithic step-down Switching Regulator with two power-ON reset timers and a watchdog timer. The regulator operates off inputs up to 36V. Low ripple Burst Mode® operation maintains high efficiency at low output current while keeping output ripple below 25mV in a typical application, with input quiescent current of just 115µA. Shutdown circuitry reduces input supply current to less than 1µA while EN/UVLO is pulled low. The reset and watchdog timeout periods are both adjustable using external capacitors. Tight accuracy specifications and glitch immunity ensure reliable reset operation without false triggering. The open collector RST pins will pull down if the monitored output voltage drops 10% below the programmed value. The LT3688 watchdog timer monitors for watchdog falling edges grouped too close together or too far apart.
  • Programmable, defeatable window watchdog timer
  • Two independently programmable power-on-reset timers
  • Programmable input undervoltage lockout with hysteresis
