4 / 15 page DC/DC Step-Down Converter IC SI-8000TM Series September 2005 Sanken Electric Co.,Ltd. I02-001EA-050910 *3 Efficiency is calculated by the following equation. *4 No.5 terminal is a SS terminal to enable soft start by connecting a capacitor. The output can be turned on and off by using a SS terminal. The output is stopped by decreasing the SS terminal voltage below VSSL and in order to perform ON/OFF operation of Vout, it is required to connect NPN transistor or the output of open collector type TTL between No.5 terminal and GND. In case that both soft and Vout ON/OFF are used, a protection measure such as limitation of current is required, as the discharge current of C3 flows across a transistor for ON/OFF operation, if the capacitance of C3 large. As a pull-up type resistor is provided inside the IC, no external voltage can be applied. In case of no use of ON/OFF, please keep it open. 4-2 Typical characteristics (Ta=25℃) (1) Efficiency η (%)= × 100 VO・IO VIN・IIN VO.ON/OFF Soft start +VO.ON/OFF C3 5 SS Soft start C3 SI-8000TFE SI-8000TFE SI-8000TFE 5 SS 5 SS SI-8000TM SI-8000TM SI-8000TM Efficiency Efficiency SI-8008TM/TFE 効率特性 Ta=25℃ Vo=5v設定時 55 60 65 70 75 80 85 00.511.5 Iout A VIN= 8v,10v,15v,20v,30v, 40v Vo=5V adjusted:R1=42kΩ R2=08kΩ Efficincy Curve SI-8008TM Efficiency Curve Vo=5V Adjusted:R1=4.2kOhm, R2=0.8kOhm 4/15 |
