Product Overview

The LT3757EMSE#PBF is a boost, flyback, SEPIC and Inverting Controller. The wide input range, current mode, DC/DC controller which is capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. It drives a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of this can be set with an external resistor over a 100kHz to 1MHz range and can be synchronized to an external clock using the SYNC pin. A low minimum operating supply voltage of 2.9V and a low shutdown quiescent current of less than 1µA, make this ideally suited for battery-operated systems.
  • Positive or negative output voltage programming with a single feedback pin
  • Current mode control provides excellent transient response
  • Programmable operating frequency (100kHz to 1MHz) with one external resistor
  • Synchronizable to an external clock
  • Internal 7.2V low dropout voltage regulator
  • Programmable input under-voltage lockout with hysteresis
  • Programmable soft-start
