Product Overview

The LTC1871IMS-1#PBF is a current-mode boost Flyback/SEPIC Controller 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 MOSFET's 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 IC's 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. It has 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.
  • Wide input range
  • Current mode control provides excellent transient response
  • ±2% RUN pin threshold with 100mV hysteresis
  • ±1% Internal voltage reference
  • Ultralow pulse skip threshold for wide input range applications
  • User-controlled pulse skip or burst mode operation
  • Output overvoltage protection
  • Capable of operating with a sense resistor for high output voltage applications
