Product Overview

The LT3999HMSE#PBF is a monolithic DC/DC Transformer Driver providing isolated power in a small solution footprint. The LT3999 has two 1A current limited power switches that switch out of phase. The duty cycle is programmable to adjust the output voltage. The switching frequency is programmed up to 1MHz and can be synchronized to an external clock for more accurate placement of switcher harmonics. The input operating range is programmed with the precision undervoltage and overvoltage lockouts. The supply current is reduced to less than 1µA during shutdown. User-defined RC time constant provides an adjustable soft-start capability by limiting the inrush current at start-up.
  • Dual 1A Switches with programmable current limit
  • ∆VIN Compensation using duty cycle control
  • Low noise topology
  • Programmable input over and undervoltage lockout
  • Cross conduction prevention circuitry
  • Programmable soft-start
  • <1µA Low shutdown current
  • High voltage
  • High frequency
