The LT3467IDDB#PBF is a step-up DC-to-DC Converter with integrated soft-start. The switching regulator combines a 42V/1.1A switch. Pin compatible with the LT1930, its low VCESAT bipolar switch enables the device to deliver high current outputs in a small footprint. The LT3467 switches at 1.3MHz, allowing the use of tiny, 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 high voltage switch on the LT3467 is rated at 42V, making the device ideal for boost converters up to 40V as well as SEPIC and flyback designs. The LT3467 can generate 5V at up to 540mA from a 3.3V supply or 5V at 450mA from four alkaline cells in a SEPIC design.
● Dedicated soft-start pin
● Uses small surface mount components
