1， Circuit board PCB description：
1.1 Name ： PW2153 Buck Circuit board
1.2 Applications ： Voltage buck converter board
1.3 VIN input voltage ： 8V-90V
1.4 VOUT output voltage ： 5V， 24V， 12V（ TheVIN>VOUT+3 condition must be met）
1.5 Introduction to Chip Functions ：
1， Buck chip：PW2153
PW2153 input voltage is 8V~120V, you can set the constant voltage output voltage value byR1,R2, R3,R4,current up to 10A(120W output power), output can be set in the range of 5V-30V,package SOP8.
2 ， Circuit diagram：
Note 1： CIN,CF2 input capacitor and COUT output capacitor must not be omitted. At the same time，CIN,CF2 should be placed next to 1 pins, as close as possible..
Note 2： The value of R5 is set according to the input voltage,calculated according to the current about 1mA, and the output false load resistance. If the current is 2mA, for example, the output is 24V, then the false load resistance is 12K (R12).
