Product Summary
The LT3467AES6 is a SOT-23 switching regulator. It combines a 42V, 1.1A switch with a soft-start function. Pin compatible with the LT1930, its low VCESAT bipolar switch enables the LT3467AES6 to deliver high current outputs in a small footprint. The LT3467AES6 switches at 2.1MHz, allowing the use of even smaller components. 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 LT3467AES6 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.
