MC34063A positive voltage negative voltage / reverse module

 1. summarize

LC-MC34063A_NV is a reverse voltage module based on chip MC34063A used to provide a reverse voltage, negative voltage module. To be able to + 5 v voltage into - 5 v voltage output. Can according to the requirements by adjusting the potentiometer to adjust output voltage.


 2.functional characteristics 

(1)MCU embedded technology.
Input voltage, output load voltage.
Easy to operate, can through the potentiometer to adjust output voltage.
Convenient module is small, easy to carry and use all kinds of occasions.


(2) technical parameters

 The input voltage range: 3.6 V - 36 V.
Range of output voltage: 1.5 V to 36 V negative output voltage regulator features; Load regulation is less than 5%.
Output current. This module IC internal switch tube is 1.5 A, but for reasons of safety and calorific value, recommend this module within the load on the power consumption is 0.5 W.Is the negative 5 v output, load within the 100 MA, suggestion is 50 MA. Note: the higher the output of the negative pressure, load ability is relative decline.


3.hardware and instructions


VIN: input voltage of 3.6 V - 36 V.
GND: public land.
VOUT: 1.5 V to 36 V.
Instructions: the working voltage VCC &gnd, not reverse connection, in order to avoid damage to the board and components.
By adjusting the potentiometer to adjust output voltage.

Need to input and output feet by one greater than 100UF electrolytic capacitors to the ground. The input and output filter capacitor is the positive input feet, negative ground. Pressure must be greater than the input and output voltage of capacitor.
