Product Overview

The LT3742EUF#PBF is a dual step-down DC/DC Switching Regulator Controller that drives high side N-channel power MOSFETs. A 500kHz fixed frequency current-mode architecture provides fast transient response with simple loop compensation components and cycle-by-cycle current limiting. The output stages of the two controllers operate 180° out of phase to reduce the input ripple current, minimizing the noise induced on the input supply and allowing less input capacitance. An internal boost regulator generates a bias rail of VIN 7V to provide gate drive for the N-channel MOSFETs allowing low dropout and 100% duty cycle operation. The LT3742 can be used for applications where both controllers need to operate independently, or where both controllers are used to provide a single higher current output.
  • Out-of-phase controllers reduce required input capacitance and power supply induced noise
  • Internal boost converter provides bias rail for N-channel MOSFET gate drive
  • Power good voltage monitor for each output
  • Programmable soft-start
