MP3430GQ - 90V Step-Up Converter

This page provides the datasheet information for the MP3430GQ, a member of the MP3430 90V Step-Up Converter family.

Description

The MP3430 is a monolithic step-up converter that integrates a power switch and a biased avalanche photodiode (APD) current monitor.

The device can double the output voltage through the APD optical receivers.

The MP3430 can provide up to 90V output.

Features

  • two accurate APD current monitoring outputs with 1:10 and 1:2 ratios, respectively. Resistor-adjustable current limiting protects the APD from optical power transients. The MP3430 includes over-current and thermaloverload protection to prevent damage in the event of an output overload. The MP3430 is available in a small 3mm×3mm QFN16 package.

The Future of Analog IC Technology DESCRIPTION The MP3430 is a monolithic step-up converter that integrates a power switch and a biased avalanche photodiode (APD) current monitor. The device can double the output voltage through the APD optical receivers. The MP3430 can provide up to 90V output. The MP3430 uses a current-mode, fixedfrequency architecture to regulate the output voltage, which provides a fast transient response and cycle-by-cycle current limiting. The MP3430 features two accurate APD current monitoring outputs with 1:10 and 1:2 ratios, respectively. Resistor-adjustable current limiting protects the APD from optical power transients. The MP3430 includes over-current and thermaloverload protection to prevent damage in the event of an output overload.
