1 / 15 page DC/DC Step-Down Converter IC SI-8000TM Series September 2005 . Sanken Electric Co.,Ltd. I02-001EA-050910 ■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 Recorder、FPD TV ●OA equipment, such as a printer ●On-board local power supply ■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. ■Key Specifications Typical Connection SI-8008T M (ADJ Type) SI-8033T M SI-8050T M SI-8120T M Input Voltage 43V Output Current 0 to 1.5A Output Voltage 0.8V (REF Voltage) 3.3V 5.0V 12.0V Efficiency (TYP) 81% (5V Set-up) 76% 81% 87% C1:220μF C2:470μF C3:1μF (At the time of soft start functional use) L1:47μH Di:SFPB66(Sanken) http://www.sanken-ele.co.jp/en/ 1/15 |
