Product Overview

The LT3571IUD#PBF is a current-mode step-up DC-to-DC Converter designed to bias avalanche photodiodes (APDs) in optical receivers with an output voltage up to 75V. The LT3571 features a high side fixed voltage drop APD current monitor with better than 10% relative accuracy over the entire temperature range. The integrated power switch, Schottky diode and APD current monitor allow a small solution footprint and low solution cost. It combines a traditional voltage loop and a unique current loop to operate as a constant-current source or constant-voltage source. The inductor-based topology ensures an input free from switching noise. The integrated high side current monitor produces a current proportional to the APD current with better than 10% relative accuracy over four decades of dynamic range in the input range of 250nA to 2.5mA. This current can be used as a reference to provide a digitally programmed output voltage via the CTRL pin.
  • Integrated Schottky diode
  • High side fixed voltage drop APD current monitor
  • Frequency synchronization
  • Constant-voltage and constant-current regulation
  • Programmable current limit protection
  • Surface mount components
  • Internal soft-start
  • Internal compensation
  • CTRL pin allows output adjustment with no polarity inversion
  • Up to 70V high APD voltage
  • <1µA Low shutdown current
