Overview

www.DataSheet4U.com LT3472 Boost and Inverting DC/DC Converter for CCD Bias DESCRIPTIO The LT®3472 dual channel switching regulator generates positive and negative outputs for biasing CCD imagers.

The device delivers up to –8V at 50mA and 15V at 20mA from a lithium-ion cell, providing bias for many popular CCD imagers.

Switching at 1.1MHz, the LT3472 uses tiny, low profile capacitors and inductors and generates low noise outputs that are easy to filter.

Key Features

  • Generates 15V at 20mA,.
  • 8V at 50mA from a Li-Ion Cell Internal Schottky Diodes VIN Range: 2.2V to 16V Output Voltages Up to ±34V Capacitor-Programmable Soft-Start Sequencing: Positive Output Reaches 88% of Final Value Before Negative Output Begins Requires Only One Resistor to Set Output Voltage Constant Switching Frequency Ensures Low Noise Outputs Available in a 10-Lead (3mm × 3mm) DFN Package U.
