The CXSU63239 boost converter contains a 0.7Ω internal switch. The IC operates at constant frequency 1MHz, allowing the use of tiny, low cost and low height inductors and capacitors. The IC operates from a 2.7V to 5.5V supply voltage and can boost supply voltage up to 40V at the output. High inrush current at start-up is eliminated using the soft-start function. Constant frequency current mode PWM architecture results in low, predictable output noise. The CXSU63239 includes cycle-by-cycle 850mA current limiting to maximum inductor current and over-temperature protection circuit. The CXSU63239 is suitable for small or medium size LCD panel of high bias voltage with a constant current to provide PDAs, and other portable devices. The CXSU63239 is available in SOT-23-5 package.
