Description

The LM3224 is a step-up DC/DC converter with a 0.15 (typ.), 2.45A (typ.) internal switch and pin selectable operat-ing frequency. With the ability to convert 3.3V to multiple outputs of 8V, -8V, and 23V, the LM3224 is an ideal part for biasing TFT displays. With the high current switch it is also ideal for driving high current white LEDs for flash applica-tions.The LM3224 can be operated at switching frequencies of 615kHz and 1.25MHz allowing for easy filtering and low noise.An external compensation pin gives the user flexibility in setting frequency compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. An external soft-start pin allows the user to control the amount of inrush current during start up. The LM3224 is available in a low profile 8-lead MSOP package.
