LT3472EDD#TRPBF

LT3472 is a dual channel switching regulator generates positive and negative outputs for biasing CCD imagers. This device delivers upto -8V at 50mA and 15V at 20mA from a lithium-ion cell, providing bias for many popular CCD imagers. Schottky diodes are internal and the output voltages are set with one resistor per channel, reducing external component count. Internal sequencing circuitry disables the negative channel until the positive channel has reached 88% of its final value, ensuring that the sum of the two outputs is always positive. Separate soft-start capacitors for each output allow the ramp of each output to be independently controlled. It is widely used in application such as CCD bias, TFT LCD bias, OLED bias, ±rail generation for op-amps etc.
