DC/DC Step-Down Converter IC
SI-8000TM Series
September 2005
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.
Package---TO252-5
Applications
DVD RecorderFPD TV
OA equipment, such as a printer
On-board local power supply
