Max15031 80V, 300mW Boost Converter and current Monitor

Maxim introduce 80V, 300mW Boost Converter and current Monitor for APD Bias Applications . The MAX15031 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) and can be used in for a wide variety of applications such as avalanche photodiode biasing, PIN biasing, or varactor biasing, and LCD displays and operates from 2.7V to 11V.
The MAX15031 includes a current monitor with more than three decades of dynamic range and monitors current ranging from 500nA to 2mA with high accuracy.
The MAX15031 is available in a thermally enhanced 4mm x 4mm, 16-pin TQFN package and operates over the -40°C to +125°C automotive temperature range.
