When using by less than 20 mA, there is a possibility that the output voltage becomes unstable. ■Recommended Operating Conditions *1: Limited by thermal protection. ■Electrical Characteristics Unit V % kHZ mV mV mV/°C A mA µA V µA Parameter Reference Voltage Efficiency Oscillation Frequency Line Regulation Load Regulation Temperature Coefficient of Reference Voltage Overcurrent Protection Starting Current Quiescent Circuit Current Circuit Current at Output OFF CE/SS* Low Level Voltage Terminal Terminal Outflow Current at Low Voltage Symbol VREF Conditions Eff Conditions FOSC Conditions ∆VOLINE Conditions ∆VOLOAD Conditions ∆VREF/∆Ta IS Conditions Iq Conditions Iq(OFF) Conditions VSSL ISSL Conditions (Ta=25°C) *: Pin 2 is the CE/SS pin. Soft start at power on can be performed with a capacitor connected to this pin.The output can also be turned ON/OFF with this pin. The output is stopped by setting the voltage of this pin to VSSL or lower. CE/SS-pin voltage can be changed with an open-collector drive circuit of a transistor. When using both the soft-start and ON/OFF functions together, the discharge current from C4 flows into the ON/OFF control transistor. Therefore, limit the current securely to protect the transistor if C3 capacitance is large. The CE/SS pin is pulled up to the power supply in the IC, so applying the external voltage is prohibited. ■Features • DIP 8 pin package • Output current: 1.5A • High efficiency: 86% (at VIN = 20V, lO = 1A, VO = 5V) • Capable of downsize a choke-coil due to IC's high switching frequency (250kHz). (Com- pared with conventional Sanken devices) • The output-voltage-variable type can vary its output voltage from 1V to 14V because of its low reference voltage (Vref) of 1V. •Wide Input Voltage Range (8 to 50V) • Output ON/OFF available • Built-in overcurrent protection and thermal protection circuits Ratings SI-8010GL (Variable type) min. typ. max. 0.97 1.00 1.03 VIN=12V, IO=1A 86 VIN=20V, IO=1A, VO=5V 250 VIN=12V, IO=1A 20 40 VIN=10 to 30V, IO=1A 10 30 VIN=12V, IO=0.1 to 1.5A ±0.5 1.6 VIN=12V 7 VIN=12V, IO=0A 400 VIN=12V, VON/OFF=0.3V 0.5 50 VSSL=0V Compact, Separate Excitation Step-down Switching Mode SI-8000GL Series ■Applications • Onboard local power supplies •OA equipment • For stabilization of the secondary-side output voltage of switching power supplies SI-8000GL SI-8000GL CE/SS 2 CE/SS 2 CE/SS C4 C4 2 VO.
