80V, 300mW Boost Converter And Current Monitor For APD Bias Applications

The MAX15031 consists of a constant-frequency pulse- width 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 MAX15031 CAN be used for a wide variety of applications such as avalanche Photodiode biasing, PIN biasing, or varactor biasing, and LCD Displays The MAX15031 operates from 2.7V to 11V. The constant-frequency (400kHz), current-mode PWM architecture provides low-noise output voltage that is easy to Filter A High-Voltage internal power Switch allows this device to boost output voltages up to 76V. Internal soft-start circuitry limits the input current when the boost converter starts. The MAX15031 features a shutdown mode to save power. By Maxim Integrated Products
