Product Overview

The LT3758EDD#PBF is a current-mode DC/DC Controller capable of generating either positive or negative output voltages. It 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 the controller 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 minimum operating supply voltage of 5.5V and a low shutdown quiescent current of less than 1µA, makes it ideal. It features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit.
  • Positive or negative output voltage programming with a single feedback pin
  • Current mode control provides excellent transient response
  • Synchronizable to an external clock
  • <1µA Low shutdown current
  • Internal 7.2V Low dropout voltage regulator
  • Programmable input undervoltage lockout with hysteresis
  • Programmable soft-start
