Pinout

The ACT4088US-T is a step-down DC-DC converter IC designed by Active-Semi. It is housed in an 8-pin SOIC package. The pin functions are as follows:
1. BS (Bootstrapped Supply): This pin is connected to an external capacitor to provide a supply voltage to the high-side gate drive.
2. IN (Input Voltage): Power input where the input voltage is supplied to the IC.
3. SW (Switch Output): This pin connects to the inductor, providing the switched output.
4. GND (Ground): Ground reference for the IC.
5. FB (Feedback): This pin receives the voltage feedback from the output to regulate output voltage.
6. COMP (Compensation): Used for external compensation to stabilize the control loop.
7. EN (Enable): A logic input to enable or disable the IC.
8. SS (Soft Start): Connects to a capacitor to control the soft-start timing.
This configuration allows the ACT4088US-T to efficiently regulate voltage by toggling the internal switch, thus stepping down the input voltage to a desired output level.
