Maxim Low-Noise Step-Up Converter Delivers Up To 600mW From Tiny TDFN

Maxim Integrated Products introduced the MAX15032, constant-frequency, pulse-width modulated (PWM), low-noise step-up converter. Designed for low-voltage systems that require a locally generated high-voltage output, this device integrates a high-voltage DMOS power switch, allowing it to boost the output up to 36V and deliver 600mW (max) of power. Additionally, it employs an internal charge-pump circuit to enable low-voltage operation from 2.7 to 11V.

The MAX15032 is well suited for applications such as avalanche-photodiode, PIN-diode, and varactor-diode biasing. It is also well suited for set-top box audio IC supplies and LCD displays.

It utilizes a current-mode PWM architecture that switches at a constant 500kHz frequency to ease filtering requirements. A shutdown input allows for low power consumption.

Available in a small, 3 x 3mm, 8-pin TDFN package, the MAX15032 is fully specified over the -40 to +125°C automotive temperature range.

Prices start at $1.05 (1000-up, FOB USA).
