Power factor correction is an important part of power management, regulating the input current consumption of electrical systems and improving the overall energy efficiency. The SSC2001S-TL application field and working principle is a power factor correction integrated circuit (integrated power management IC) manufactured by SST, a leader in the semiconductor markets.

The SSC2001S-TL IC provides efficient, accurate and cost-effective power factor correction and system power management, allowing electronic systems to operate with better stability and power efficiency. It is capable of automatically adjusting the phase of the input voltage and the angle between the rectified current and the voltage, thereby reducing power loss and improving power factor. The wide input voltage range of the IC provides excellent compatibility with AC or DC input supplies of 3.3V to 10V, supporting any type of power supply from wall-mounted adapters to internal PC power supplies.

This power factor correction IC also takes into account the transient input power changes, and it can accurately correct the power factor with fast reaction time. It also features overload protection, which is triggered when the monitored output power exceeds the safe level and the IC will instantly shut down the power supply to protect the entire system. Thanks to these features, the SSC2001S-TL power factor correction is a reliable and energy efficient solution for smart home appliances, communication equipment and office equipment.

The schematics of the SSC2001S-TL PFC IC is shown in Figure 1 below. It can be seen that the circuitry consists mainly of two main components, a rectifying circuit and a power factor correction circuit. The rectifying circuit converts the alternating current (AC) into direct current (DC) using rectifiers, and the power factor correction circuit uses filters like inductors and capacitors to shape the input current waveform to replicate the voltage waveform more closely, which reduces power losses and improves power factor. The SSC2001S-TL control IC uses Pulse Width Modulation (PWM) to drive the power factor adjustment circuit.
