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.
