The MAX15032 constant-frequency, pulse-width-modulating (PWM), low-noise boost converter is intended for low-voltage systems that need a locally generated high voltage. This device is capable of generating low-noise, high output voltages, with an output power capability up to 600mW with a 2.9V input voltage. This device can be used for a wide variety of applications, such as PIN or varactor diode biasing and LCD displays. The MAX15032 operates from +2.7V to +11V.

The constant-frequency (500kHz), current-mode PWM architecture provides low-noise output voltage that is easy to filter. A high-voltage internal lateral DMOS power switch allows this device to boost output voltages up to 36V. The MAX15032 features a shutdown mode to save power.

The MAX15032 is available in a small thermally enhanced 3mm x 3mm 8-pin TDFN package and is specified for operation over the -40°C to +125°C automotive temperature range.
