Product Overview

The LTC1871EMS-7#PBF is a current mode boost flyback and SEPIC Controller optimized for driving 6V rated MOSFETs in high voltage applications. The LTC1871-7 works equally well in low or high power applications and requires few components to provide a complete power supply solution. The switching frequency can be set with an external resistor over a 50kHz to 1MHz range and can be synchronized to an external clock using the MODE/SYNC pin. Burst Mode operation at light loads, a low minimum operating supply voltage of 6V and a low shutdown quiescent current of 10µA make the LTC1871-7 well suited for battery-operated systems. For applications requiring constant frequency operation, burst mode operation can be defeated using the MODE/SYNC pin.
  • Current mode control provides excellent transient response
  • High maximum duty cycle (92% typical)
  • Programmable operating frequency with one external resistor
  • Synchronizable to an external clock up to 1.3 x fOSC
  • User-controlled pulse skip or Burst Mode® Operation
  • Output over-voltage protection
  • Can be used in a No RSENSE™ Mode for VDS <36V
