DESIGN FEATURESвЂ‰L Complete APD Bias Solution in 60mm2
with On-the-Fly Adjustable Current
By Xin (Shin) Qi
Limit and Adjustable VAPD
Introduction
The overriding factor limiting functionality in fiber-optic communication
systems is available space. A compact
APD (avalanche photo diode) bias
solution with a high degree of feature
integration is the key to breaking
new ground in system size and performance. The LT3571 offers such a
solution in a tiny 3mm Г— 3mm QFN
package.
The LT3571 combines a current
mode step-up DC/DC converter and
a high side fixed voltage drop APD
current monitor with an integrated
75V power switch and Schottky diode.
The combination of a traditional voltage loop and a unique current loop
allows customers to set an accurate
APD current limit at any given bias
voltage. The integrated high side current monitor provides an 8% accurate
current that is proportional to the load …
