■Features
• Surface-mount package (TO263-5)
• Output current: 1.5A
• High efficiency: 77 to 88%
• Requires only 4 discrete components
• Internally-adjusted phase correction and
output voltage
• Capable of downsizing a choke-coil due to IC's
high switching frequency (125 kHz). (Com-
pared with conventional Sanken devices)
• Built-in foldback-overcurrent and thermal
protection circuits
• Output ON/OFF available (Circuit current at
output OFF: 200
µA max)
• Soft start available by ON/OFF pin Conditions

*: Limited by Ta–PD characteristics
*: Pin 5 is the ON/OFF 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.
ON/OFF-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 C3
flows into the ON/OFF control transistor. Therefore, limit the current securely to protect the
transistor if C3 capacitance is large.
The ON/OFF pin is pulled up to the power supply in the IC, so applying the external voltage is
prohibited.
