APW7078XI-TRL 茂达说明Single Step-up DC/DC ControllerGeneral DescriptionThe APW7078 is a single PWM, step-up DC-DC control-ler with low operating voltage application integrating soft- start and short circuit detection function. The oscillator switching frequency on chip can be operated by terminat- ing OSC pin to connect capacitor and resistor for adjust- able 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) ce- ramic output capacitors.
