illustrate

The LM3224 is a step-up DC/DC converter with 0.15 (typical), 2.45A (typ) internal switching and pin-selectable operating frequency. The LM3224's ability to convert multiple outputs from 3.3V to 8V, -8V and 23V is an ideal part of a biased TFT display. Along with high-current switching, it is also ideal for driving high-current white LED flash applications. The LM3224 can operate at a switching frequency of 615kHz and 1.25MHz that allow easy screening and low noise. An external compensation pin allows the user to compensate at a set frequency, which makes it possible to use small, low ESR ceramic capacitor output flexibility. An external soft-start pin allows the user to control the inrush current during start-up. The LM3224 is a low-profile 8-lead MSOP package.
