■General Descriptions
SI-8000TM series has 300kHz oscillation frequency, so it contributes miniaturization of a chalk coil. Therefore, it realizes a compact and high efficient power supply together with TO 252-5 package (compatible:SC-63) .
SI-8000TM series has the function required for switching regulators and protection circuits such as over-current, and overheating. With only four discrete components, it realizes a high efficient switching regulator without adjustment. 1.5A output current by compact power surface mount package.

■Features
●1.5A output current by compact power surface mount package.
● High Efficiency 81% (at VIN=15V, Io=0.5A,Vo=5V)
● Requires only four discrete components. (C3: required for soft start.)
●Built-in Oscillation circuit (oscillation frequency : 300kHz (TYP))
●Constant current type overcurrent protection and overheating protection.
●Soft start function. (ON/OFF function available. Output OFF at Low level.)
● Low consumption current at Output OFF

■Applications
●DVD Recorder、 FPD TV
●OA equipment, such as a printer
●On-board local power supply
