KB3308 DESCRIPTION
The KB3308 step-up converter is designed for small or medium size LCD panel of high bias voltage with a constant current to provide PDAs, and other hand-held devices. It features a fast 1.2 MHz current-mode PWM control with a built-in 0.2Ω N-MOS that allows for smaller capacitor and inductor. Fault condition protection uses cycle-by-cycle current limiting to sense maximum inductor current and thermal protection. Also included soft-start eliminates inrush current during start-up.The KB3308 is available in 5-pin SOT23-23-5 packages.
