LT3467AES6#TRMPBF Datasheet PDF - Linear Technology

●The LT3467AES6#TRMPBF is a 1.1A Step-up DC/DC Converter with integrated 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 LT3467A switches at 2.1MHz, allowing the use of 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. Constant frequency current mode PWM architecture results in low, predictable output noise that is easy to filter. The high voltage switch on the LT3467A is rated at 42V, making it ideal for boost converters up to 40V as well as SEPIC and flyback designs. The LT3467A can generate 5V at up to 430mA from a 3.3V supply or 15V at 135mA from a 3.3V supply.
