The LT3571EUD#PBF from LT is a current-mode step-up DC/DC converter capable of biasing avalanche photodiodes (APDs) with an output voltage up to 75V. This device integrates a power switch, Schottky diode, and an APD current monitor, enabling a compact solution footprint and reduced cost. It operates as a constant-current or constant-voltage source, utilizing an inductor-based topology for noise-free input.
The converter features a high-side fixed voltage drop APD current monitor with better than 10% relative accuracy over the entire temperature range. The integrated monitor provides a current proportional to the APD current, with accuracy better than 10% over four decades of dynamic range. This current can be used to digitally program the output voltage via the CTRL pin.
Key electrical specifications include a wide input voltage range of 2.7V to 20V, an adjustable switching frequency from 250kHz to 2MHz, and programmable current limit protection. The device also offers frequency synchronization, internal soft-start, and internal compensation.
The LT3571EUD#PBF is available in a 3mm x 3mm 16-lead QFN package, suitable for surface mount applications. Its low shutdown current of less than 1μA makes it efficient for power-sensitive designs.
The maximum output voltage is 75V.
The internal switch has a current rating of 370mA.
The input voltage range is from 2.7V to 20V.
The frequency can be adjusted from 250kHz to 2MHz.
The operating ambient temperature range is from -40°C to 125°C.
It is available in a 3mm x 3mm 16-lead QFN package.
The RoHS status is RoHS3 Compliant.
