Produktu pārskats

The LT3959IFE#PBF is a current-mode DC/DC Controller capable of regulating either positive or negative output voltages from a single feedback pin. It can be configured as a boost, SEPIC or inverting converter. It features an internal low side N-channel MOSFET rated for 6A at 40V and driven from an internal regulated supply provided from VIN or DRIVE. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3959 can be set over a 100kHz to 1MHz range with an external resistor, or can be synchronized to an external clock using the SYNC pin. It features soft-start and frequency fold back functions to limit inductor current during start-up and output short-circuit. A window comparator on the FBX pin reports via the PGOOD pin, providing output voltage status indication.
  • Positive or negative output voltage programming with a single feedback pin
  • PGOOD output voltage status report
  • Internal 6A/40V power switch
  • Programmable soft-start
  • Synchronizable to an external clock
  • <1µA Low shutdown current
  • INTVCC Regulator supplied from VIN or DRIVE
  • Programmable input under voltage lockout with hysteresis
