SI-8008TM

DC-DC Step-Down Converter IC

■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.
