TP1000
The TP1000 is a high-performance AC/DC power controller that uses Pulse Frequency Modulation (PFM) mode. The flyback circuit operates in Discontinuous Conduction Mode (DCM). The chip has various built-in fault protection circuits, ensuring high reliability. The TP1000 provides precise constant voltage/constant current (CV/CC) control. Stable and reliable system operation is achieved without optocouplers, secondary control circuits, or loop compensation circuits, significantly simplifying the design of low-power CV/CC power converters. This device uses innovative control technology to provide extremely tight output voltage and current regulation. The TP1000 controller is highly efficient and has low no-load power consumption, typically 100mW@220Vac. It is suitable for CV/CC power converters and adapters with a wide input voltage range, output power of 0.5W-10W, and output voltage of 3-12Vdc.
