The LT3571IUD#PBF is a current mode step-up DC/DC converter from ADI Electronics, capable of biasing avalanche photodiodes (APDs) with an output voltage up to 75V. It integrates a power switch, Schottky diode, and an APD current monitor with better than 10% relative accuracy over the entire temperature range.
This converter operates with a wide input voltage range of 2.7V to 20V and features an adjustable switching frequency from 250kHz to 2MHz. It supports both constant-current and constant-voltage regulation, making it versatile for various applications. The integrated high-side current monitor provides a current proportional to the APD current, usable for digitally programmed output voltage adjustment via the CTRL pin.
The LT3571IUD#PBF is available in a compact 3mm x 3mm 16-lead QFN package, suitable for surface mount applications. Its low shutdown current of less than 1µA and internal compensation contribute to a small solution footprint and low solution cost.
The input voltage range is 2.7V to 20V.
The maximum output voltage is 75V.
It is offered in a 16-lead QFN package (3mm x 3mm).
