Product Overview

The LTC1871EMS-1#PBF is a wide input range current mode boost flyback or SEPIC Controller that drives an N-channel power MOSFET and requires very few external components. It eliminates the need for a current sense resistor by utilizing the power MOSFETs on-resistance, thereby maximizing efficiency. Higher output voltage applications are possible with the LTC1871-1 by connecting the SENSE pin to a resistor in the source of the power MOSFET. The ICs operating 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. The LTC1871-1 differs from the LTC1871 by having a lower pulse skip threshold, making it ideal for applications requiring constant frequency operation at light loads. The lower pulse skip threshold also helps maintain constant frequency operation in applications with a wide input voltage range.
  • High efficiency (no sense resistor required)
  • Current mode control provides excellent transient response
  • High maximum duty cycle (92% typical)
  • Ultra low pulse skip threshold for wide input range
  • 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
  • Internal 5.2V low dropout voltage regulator
  • Output over-voltage protection
  • Capable of operating with a sense resistor for high output voltage
