EC9215-Step-Up DC/DC Controller
General description
The EC9215 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 EC9215 is available in a Pb‐free, SOP‐8L and TSSOP-8L package.
