Product Overview

The LT8610IMSE#PBF is a 42V 2.5A high speed synchronous monolithic Step-down Regulator that 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 under-voltage lockout or to shut down the LT8610 reducing the input supply current to 1μA. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT is within ±9% of the programmed output voltage as well as fault conditions.
  • Ultralow quiescent current Burst Mode® operation (2.5μA IQ regulating 12VIN to 3.3VOUT)
  • <10mVP-P Output ripple
  • High efficiency synchronous operation
  • 96% Efficiency at 1A, 5VOUT from 12VIN
  • 94% Efficiency at 1A, 3.3VOUT from 12VIN
  • Fast minimum switch-on time (50ns)
  • Low dropout under all conditions (200mV at 1A)
  • Allows use of small inductors
  • Low EMI
  • 200kHz to 2.2MHz Adjustable and synchronizable
  • Current mode operation
  • Accurate 1V enable pin threshold
  • Internal compensation
  • Output soft-start and tracking
