■ 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.
