The Analog Devices LT3472 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. Schottky diodes are internal and the output voltages are set with one resistor per channel, reducing external component count.

Internal Schottky Diodes
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
