PIC16F1825
110V轉24V、12V、5V和3.3V的供應器，您需要以下零件：PIC16F1825 微控制器
220V到110V的降壓變壓器
24V的線性穩壓器
12V的開關穩壓器
5V的線性穩壓器
3.3V的線性穩壓器
適當的散熱器
陶瓷電容和電解電容
積層電容
整流二極管
電位計
電阻
以下是程式碼框架，它可以用來控制這個供應器的電路：
#include <xc.h>
#include <stdint.h>
// Define oscillator frequency
#define _XTAL_FREQ 8000000
// Define output pins for each voltage level
#define V24 LATBbits.LATB0
#define V12 LATBbits.LATB1
#define V5 LATBbits.LATB2
#define V3 LATBbits.LATB3
void main(void)
{
// Configure oscillator
OSCCONbits.IRCF = 0b111; // Set oscillator frequency to 8 MHz
// Configure input/output pins
TRISBbits.TRISB0 = 0; // Set RB0 as output for 24V
TRISBbits.TRISB1 = 0; // Set RB1 as output for 12V
TRISBbits.TRISB2 = 0; // Set RB2 as output for 5V
TRISBbits.TRISB3 = 0; // Set RB3 as output for 3.3V
// Main loop
while (1)
{
// Generate 24V from transformer output
// Use a linear regulator to regulate voltage to 24V
// Generate 12V from transformer output
// Use a switch-mode regulator to regulate voltage to 12V
// Generate 5V from transformer output
// Use a linear regulator to regulate voltage to 5V
// Generate 3.3V from 5V output
// Use a linear regulator to regulate voltage to 3.3V
// Output voltages to corresponding pins
V24 = 1;
V12 = 1;
V5 = 1;
V3 = 1;
}
}
