LM2662 Negative Voltage Converter Module

Overview:
LC LM2662 positive pressure  conversion negative pressure module carry a LM2662 high precision voltage conversion chip, it can conversion 1.5V-5.5V Positive voltage to corresponding the negative voltage.

Function and characteristics:
Effective input voltage of 1.5 V to 5.5 V
Internal crystals of oscillation frequency is adjustable
A typical output resistance 3.5 ohms

Hardware and instructions:
Size: 20*10mm
The board function description:
V + : positive voltage input
GND: switching power supply
V - : negative voltage output
When the FC in short two solder joint can choose internal crystal frequency is 150 KHZ, disconnected internal crystals to 20 KHZ;

Note:
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

Package Include:
1x LM2662 Module
