SNVSC22A October 2023 – March 2024 LM51772
ADVANCE INFORMATION
The LM51772 provides slope compensation to ensure stable operation and the best transient performance over a wide operating range. According to peak current mode control theory, slope compensation is required at operation with duty cycle greater than 50%.
First a correction factor needs to be calculated from Equation 7
Based on the calculated correction factor the slope compensation can be programmed through I2C or by connecting a resistor to ADDR/Slope pin. See Table 8-4 for selecting the resistor value based on the slope compensation correction factor.
