LT LT3482EUD#TRPBF

升压升压，充电泵2.5V16V280mA（开关）

Overview

The LT3482EUD is a fixed frequency current mode step-up DC/DC converter with voltage doubler designed to bias avalanche photodiodes (APDs) in optical receivers. It can provide up to 90V output. The LT3482EUD features high side APD bias current monitoring with better than 10% relative accuracy over the entire temperature range. The integrated power switch, Schottky diodes and APD bias current monitor allow a small converter footprint and low solution cost. Constant switching frequency results in predictable output noise that is easy to filter. The inductor-based topology ensures an input free from switching noise. An integrated high side current monitor produces a current proportional to APD bias current with better than 10% relative accuracy over four decades of dynamic range in the input range of 250nA to 2.5mA. This APD bias current can be used as a reference to provide a digitally programmed output voltage via the CTRL pin. The LT3482EUD is available in the tiny footprint (3mm × 3mm) 16-lead QFN package.
