*: 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
