The main parameters:
Working voltage: 3V to 15V
Standby current: 1mA
Output voltage: -1.25V to -15V continuously adjustable
Conversion efficiency: >83%
Output current: 300mA (the higher the input voltage, the greater the output current)
Module volume: 29.0mm*24.0mm*9.2mm
Adjustment method: miniature adjustable resistor, use clock screwdriver to adjust

Typical ripple factor (VPp):
Input 12V output-5V load 300mA = 180mVPp
Input 12V output-5V load 500mA = 245mVPp
Input 12V output -12V load 100mA = 60mVPp
Input 12V output -12V load 300mA = 160mVPp
Input 12V output-5V load 300mA = 180mVPp
Input 12V output-5V load 500mA = 245mVPp
Input 12V output -12V load 100mA = 60mVPp
Input 12V output -12V load 300mA = 160mVPp
Note: If a solid low ERS capacitor above 470uf is added to the output, VPp can be reduced to below 30mV
Product Usage:
LCD screen power supply, logic circuit power supply, DVD, EVD, operational amplifier circuit, single-chip microcomputer, communication equipment, signal processor, and other circuits or modules that require negative voltage power supply. The module can provide a maximum current of 300mA and an output current of 500mA in a short time.

Precautions:
The input polarity must not be reversed, and the input high voltage must not exceed 15V;
It is recommended to use a non-inductive screwdriver to adjust the voltage, try to rotate it slowly, and do not rotate the potentiometer too much, otherwise the output voltage will break down the chip after it exceeds the -15V limit.
