MP3430

90V Step-Up Converter

with APD Current Monitor

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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.



2.7V-to-5.5V Input Voltage

100V/1Ω NFET with 0.9A Limit

Up to 90V Output Voltage

50ns APD Current Monitoring Response

Speed

1.3MHz Fixed Switching Frequency

Internal Compensation and Soft-Start

High-Side APD Current Monitor with less

than ±5% Tolerance.



The MP3430 uses a current-mode, fixed-

frequency architecture to regulate the output

voltage, which provides

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.



1:10 and 1:2 Ratio Outputs for APD Current

Monitoring

Thermal-Shutdown Protection

Programmable APD Over-Current Limit and

Protection



3×3mm QFN16 Package

The MP3430 includes over-current and thermal-

overload protection to prevent damage in the

event of an output overload.

APPLICATIONS



APD Biasing

PIN Diode Biasing

Optical Receivers and Modules

Fiber-Optic–Network Equipment

The MP3430 is available in a small 3mm×3mm

QFN16 package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
