Working Principle

This power management IC has excellent pulse width modulation functions, allowing it to achieve higher conversion efficiency and output stability. The PWM controller takes the switching frequency as the main parameter. Its main feedback control circuit consists of a volter-divider, error amplifier, driver, and thermal protection circuit.

The volter-divider divides the output voltage to an ideal internal reference voltage. The error amplifier compares the input voltage with the internal reference voltage and provides a feedback voltage. The driver provides an appropriate drive signal according to the feedback voltage, which controls the external MOSFETs to adjust the output voltage. Protective functions such as overvoltage protection, foldback current limitation, over temperature protection, and short circuit protection are also built into the circuit.

S-1701U3024-M5T1G is highly efficient, reliable and accurate PWM controller, providing users with the best power performance and protection. This integrated circuit is powerful and cost-effective, and is ideal for high performance applications in many market segments.
