LM2662 Switching Voltage Stabilizer Positive Pressure Conver

Date:2024-01-19 Views:

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 features
1.Effective input voltage of 1.5V to 5.5V
2.Internal crystals of oscillation frequency is adjustable
3. A typical output resistance 3.5 ohms

Hardware introduction and description
1.Size: 20*10mm
2.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;

When the input voltage is less than 3.5V LV place two bonding pad should be short, when the input voltage is greater than 3.5V to be disconnected.
