คำอธิบาย 3.2 พิน

• วี: Input positive (+) voltage. Connect your DC power source here.
• จีเอ็นดี: Input and Output negative (-) / Ground. This is the common ground for both input and output.
• โว้: Output positive (+) voltage. Connect your load requiring the boosted voltagอีที่นี่

3.3 เอาท์พุทVoltage Selection (for adjustable models)

Some models allow for output voltage selection via solder pads or external resistors. The specific model (WALFRONTi1zh84cdtw-12) is listed as 6V, with other options available. If your module has selectable output pads, ensure the correct pad is soldered or configured for your desired output voltage (5V, 6V, 9V, 12V)

For models where output voltage is set by an external resistor (R1), refer to the following formula and table:

R1(KΩ) = 10 * (Vout / 0.6 - 1)

Figure 5: Diagram showing the location of resistor R1 for output voltage setting and R3 for current limit programming. A table provides example R1 values for different output voltages (3.7V, 4.2V, 5V, 6V, 7.5V, 9V, 10V, 12V).

3.4 Current Limit Programming

The R3 resistor programs the peak switch current. The resistor value should be between 10kΩ and 100kΩ. The current limit will be set from 2.5A to 0.5A according to the formula:

I_in = 48000 / R3

ที่ฉัน_in is the input current limit in Amperes and R3 is the resistance in Ohms.
