Description

SI-8008TM series attains an oscillation frequency of 300kHz, and has an integrated miniaturized choke coil, allowing it to serve as a high efficiency power supply in a compact TO-252-5 (SC-63) package.
SI-8008TM series regulators provides various features and protection functions (overcurrent and thermal protection) which are necessary for switching regulators.
Only 6 external components are required, and provides high efficiency switching regulation without any need for adjustment.
Device supplies 1.5A output current in a compact surface mount package.

Application

・DVD recorders, FPD TV
・OA equipment (printers, etc)
・On-board local power supplies

Features

・High efficiency: 81% (VIN=15V, Io=0.5A)
・Requires only 6 discrete components (C3 required for soft start)
・Built-in reference oscillator (Oscillating frequency: 300kHz(TYP))
・Built-in drooping-type-overcurrent and thermal protection circuits
・Built-in soft start function (Output ON/OFF available. Output OFF at low)
・Low current consumption during off
