4 Summary

This application note delivers a low cost, high-precision and small-sized power supply design for the negative-voltage-biased APD application with TPS61391. The output voltage is tightly regulated at -90 V regardless of the line load change. It is of small ripple and good dynamic performance. This circuit can cooperate with the trans-impedance amplifier LMH32401 to form a detection circuit for light detection and ranging (LIDAR) applications, laser distance measurement applications or various robot LIDAR applications.
