LM7660 Switching voltage stabilizer positive conversion to negative voltage

LM7660 Switching voltage stabilizer positive conversion to negative  voltage

1. Overview
LC LM7660 positive voltage conversion to negative voltage module carry a LM7660 high precision voltage conversion chip, it can conversion 1.5V-10V Positive voltage to corresponding the negative voltage


2.The function and characteristics
● Effective range of input voltage: 1.5 V to 10 V
● Low working current
● With high voltage and power conversion efficiency


3. Introduced the hardware and instructions
● Size: 20*10mm
● The board function description:
   V + : positive voltage input;
   GND: switching power supply;
   V - : negative voltage output
   FC in 2 solder should always keep a disconnect, when the input voltage is less than 3.5 V LV place two bonding pad should be short, when the input voltage is greater than 3.5 V to be disconnected.
