ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the
specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
ELECTRICAL CHARACTERISTICS
Note 1: Junction Temperature TJ is calculated from the ambient temperature TA and ower dissipation PD
according to the following formula: TJ = TA + PD X 220°C/W

DESCRIPTION
1
RUN
Power down control pin. Forcing this pin above 1.5V enables the device. Forcing this
pin below 0.3V shuts down the device.
2
GND
Ground pin.
3SW
Switching node.
4V
IN
Power supply pin
5VFB/ V
OUT
Adjustable Version: VFB, Feedback Input Pin. Connect FB to the center point of the
external resistor divider. The feedback threshold voltage is 0.6V.
Fixed Output Version: VOUT, Output Voltage Feedback Pin. An internal resistive
divider drops the output voltage down for comparison to the internal reference voltage.
___________________________ THERMAL
RESISTANCE
Thermal Resistance is specified with approximately 1 square inch of 1 ounce copper.
