Capable of generating 12V at 430mA from a 5V input, Loop compensation can be either internal or external, giving the user flexibility in setting loop compensation and allowing optimized transient response with low ESR ceramic output capacitors. Soft-start is controlled with an external capacitor which determines the input current ramp rate during start up. , LTC and LT are registered trademarks of Linear Technology Corporation.
