Texas Instruments High-Performance Analog PMIC - PMIC - PFC (Power Factor Correction) - UC2852D UC2852D

The UC2852D from Quarktwin Technology Ltd. is a low-cost power factor correction (PFC) integrated circuit designed for applications requiring high efficiency and minimal external components. It achieves a power factor greater than 0.99, making it suitable for low-cost applications in the 50 to 500 watt range. The device features controlled on-time boost PWM, zero-current switching, and limited peak current, which helps to maintain performance while reducing noise generation. The UC2852D operates with a supply voltage of up to 30V and includes protection features such as under-voltage lockout and peak-current limiting. It is specified for operation in a temperature range of -40¬8C to +85¬8C and is available in an 8-pin SOIC package. The device's design allows for higher peak switch currents compared to continuous PFCs, while requiring fewer external components and smaller inductors, thus simplifying the overall circuit design.
