TC2525GA-GB
product description
TC2525GA/TC2525GB is a high-performance power controller for battery chargers and adapters, with built-in power transistors. The chip uses pulse frequency modulation (PFM) to establish a discontinuous conduction mode (DCM) flyback power supply.
TC2525GA/TC2525GB provides precise constant voltage, constant current (CV / CC) does not require optocoupler and secondary control circuit adjustment. Eliminates the need for loop compensation circuits while maintaining good stability. TC2525GA/TC2525GB can achieve good linear regulation rate and load regulation rate, as well as higher average efficiency, meeting the no-load power consumption of less than 75mW@230V.
TC2525GA/TC2525GB has a proprietary output cable voltage drop compensation function, that is, output line loss compensation. The line loss compensation value can be adjusted, which can effectively compensate for the loss voltage drop on the output line.
