LV5256GP
Output Voltage Setting Method
The LV5256GP can produce any arbitrary output voltage. The output voltage is set by the resistor inserted between the
IN pin (pin 16) and GND, and IN pin and output voltage.
The calculating formula for setting the output voltage by using the output voltage setup lower-side resistor R1 and the
output voltage setup upper-side resistor R2 is as follows:
Output voltage
(Step-down) V1 or V2
(Step-up) VOUT1 or VOUT2
