Product Overview

The LT8609IMSE#PBF is a compact, high efficiency, high speed synchronous monolithic step-down Switching Regulator that consumes only 1.7µA of quiescent current. The LT8609 can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers which require high transient loads. 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 10mV. A SYNC pin allows synchronization to an external clock or spread spectrum modulation of switching frequencies for low EMI operation. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability.
  • Ultralow quiescent current Burst Mode® operation
  • <2.5µA IQ Regulating 12VIN to 3.3VOUT
  • <10mVP-P Output ripple
  • High efficiency 2MHz synchronous operation
  • >93% Efficiency at 1A, 5VOUT from 12VIN
  • 2A Maximum continuous output
  • 3A Peak transient output
  • 45ns Fast minimum switch-on time
  • Spread spectrum frequency modulation for low EMI
  • Allows use of small inductors
  • Low dropout
  • Peak current mode operation
  • Accurate 1V enable pin threshold
  • Internal compensation
  • Output soft-start and tracking
