MP3430 90V Step-Up Converter with APD Current Monitor (1:10 or 1:2 ratio) with 5% Accuracy

Product Detail

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, fixed-frequency 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 thermal-overload protection to prevent damage in the event of an output overload.?The MP3430 is available in a small 3mm?mm QFN16 package.
