The CXSU63175 is a single PWM, step‐up DC‐DC controller with low operating voltage application integrating softstart and short circuit detection function. The oscillator switching frequency on chip can be operated by terminating OSC pin to connect capacitor and resistor for adjustable operating frequency. Soft‐start is adjusted with the external capacitor, which sets the input current ramp. Besides, the external compensation FB pin will apply the flexibility in the dynamic loop status, which allows using small and low equivalent series resistance (ESR) ceramic output capacitors. The CXSU63175 is available in a Pb‐free, SOP‐8 and TSSOP‐8package.The CXSU63175 is a single PWM, step‐up DC‐DC controller with low operating voltage application integrating softstart and short circuit detection function.
