General Description

The LT®8610 is a compact, high efficiency, high speed synchronous monolithic step-down switching 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.

Key Features

  • n Wide Input Voltage Range: 3.4V to 42V n Ultralow Quiescent Current Burst Mode® Operation: 2.5μA IQ Regulating 12VIN to 3.3VOUT Output Ripple < 10mVP-P n High Efficiency Synchronous Operation: 96% Efficiency at 1A, 5VOUT from 12VIN 94% Efficiency at 1A, 3.3VOUT from 12VIN n Fast Minimum Switch-On Time: 50ns n Low Dropout Under All Conditions: 200mV at 1A n Allows Use Of Small Inductors n Low EMI n Adjustable and Synchronizable: 200kHz to 2.2MHz n Current Mode Operation n Accur.
