Win Source Electronics PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - LT3472EDD#TRPBF 94757-LT3472EDD#TRPBF

The LT3472EDD#TRPBF is a dual-channel DC/DC switching regulator designed to generate both positive and negative output voltages, specifically 15V at 20mA and -8V at 50mA from a lithium-ion cell. It operates within a voltage input range of 2.2V to 16V and can produce output voltages up to ¬±34V. The device features internal Schottky diodes, which help reduce external component count, and requires only one resistor to set the output voltage for each channel. The LT3472 operates at a constant switching frequency of 1.1MHz, ensuring low noise outputs that are suitable for applications requiring clean power. It includes a capacitor-programmable soft-start feature and has built-in sequencing that allows the positive output to reach 88% of its final value before the negative output begins, preventing negative voltage spikes. The regulator is housed in a compact 10-lead (3mm x 3mm) DFN package, making it suitable for space-constrained designs. This product is particularly applicable for biasing CCD imagers, TFT LCDs, and OLED displays, as well as for rail generation in operational amplifiers. The LT3472EDD#TRPBF is rated for an extended operating temperature range of -40¬8C to 85¬8C, making it versatile for various environmental conditions.
