The document serves as a design guide for the XL70XX series of high-voltage buck-boost regulators. It includes a quick selection table listing specific models (XL7005A, XL7015, XL7025, etc.) with their input voltage ranges, switch currents, and efficiency ratings. The guide also provides typical application circuit diagrams for various models in the series. This manual is written in Chinese.
| Input Voltage Range | 5V~100V |
|---|---|
| Switching Frequency | 150KHz |
| Package Type | SOP8 -EP |
The output voltage is calculated using the formula VOUT = 1.25*(1+R2/R1), where R1 and R2 are external resistors.
The recommended range for resistor R1 is 1KΩ to 10KΩ.
Adding a CFF capacitor can solve the overshoot problem.
No, input and output capacitors are necessary for smoothing filtering and absorbing spikes.
