Product Overview

The LT8620IUDD#PBF is a compact high-efficiency high-speed synchronous monolithic step-down Switching Regulator accepts a wide input voltage range up to 65V and consumes only 2.5µA of quiescent current. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple Burst Mode® operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shutdown the LT8620 reducing the input supply current to 1µA. A capacitor on the TR/SS pin programs the output voltage ramp rate during startup.
  • Safely tolerates inductor saturation in overload
  • Low EMI
  • Internal compensation
  • Output soft-start and tracking
  • Fast 30ns minimum switch-ON time
  • Accurate 1V enable pin threshold
  • 250mV at 1A Low dropout under all conditions
