General Description

The MAX15061 consists of a constant-frequency pulsewidth modulating (PWM) step-up DC-DC converter with an internal switch and a high-side current monitor with high-speed adjustable current limiting.

This device can generate output voltages up to 76V and provides current monitoring up to 4mA (up to 300mW).

The MAX15061 can be used for a wide variety of applications such as avalanche photodiode biasing, PIN biasing, or varactor biasing, and LCD displays.

Overview

19-5034; Rev 0; 10/09 80V, 300mW Boost Converter and Current Monitor for APD Bias.

Key Features

  • a shutdown mode to save power. The MAX15061 includes a current monitor with more than three decades of dynamic range and monitors current ranging from 500nA to 2mA with high accuracy. Resistor-adjustable current limiting protects the APD from optical power transients. A clamp diode protects the monitor’s output from overvoltage conditions. Other protection features include cycle-by-cycle current limiting of the boost converter switch, undervoltage lockout, and thermal shutdown if the die tempera.
