Product Summary

The LT3467IS6#PBF is a Step-Up DC/DC Converter. The LT3467IS6#PBF combines a 42V, 1.1A switch with a soft-start function. Pin compatible with the LT1930, its low VCESAT bipolar switch enables the device to deliver high current outputs in a small footprint. The LT3467IS6#PBF switches at 1.3MHz, allowing the use of tiny, low cost and low height inductors and capacitors. High inrush current at start-up is eliminated using the programmable soft-start function. A single external capacitor sets the current ramp rate. A constant frequency current mode PWM architecture results in low, predictable output noise that is easy to filter. The applications of the LT3467IS6#PBF include Digital Cameras, White LED Power Supplies, Cellular Phones, Medical Diagnostic Equipment, Local 5V or 12V Supplies, TFT-LCD Bias Supplies and xDSL Power Supplies.
