General Description

The SI-8008TM DC voltage regulator is a DC-to-DC buck convertor that attains an oscillation frequency of 300 kHz, and has an integrated miniaturized choke coil, allowing it to serve as a small, high efficiency power supply in a compact TO252-5 (SC-63) package.

The switching regulator function realizes a high efficiency switching regulator operation without adjustment, requiring only six external support components, and an optional capacitor for soft start operation and an optional transistor for on/off control.

The SI-8008TM includes overcurrent and overheating protection circuits.
