ON/OFF pin is pulled up to Vin inside of the DC-DC Converter. If ON/OFF pin is
left open, the DC-DC Converter shall be “ON”. This pin will be pulled down to GND
inside the DC-DC Converter when OCP or OTP events occur. Please do NOT
connect this pin to Vin with low impedance line, so as not to damage the

The above derating limits apply to this product soldered directly to 101.6*180mm*1.6mm PCB (double-sided,
with 70um copper). Any adjacent parts of high temperature may cause overheating. For reliable operation,
please ensure that the FET temperature of this product is maintained below 120°C and the inductor
temperature is below 106°C.
7. Operation information
7. 1 Adjusting the Output Voltage
The output voltage can be adjusted from 0.8V to 1.8V by connecting a resistor between
TRIM-pin(7,8Pin) to GND-pin(3,4Pin).
The following equation gives the required external-resistance value to adjust the output voltage to the
required Vout.
