The Tc1252e is a cost-effective and reliable power conversion control chip (current mode PWM controller for forward and flyback applications) for AC-DC switching power supply systems, especially ATX power supplies.
The TC1252E has output overload protection without the need to detect VCC voltage, which improves the safety of the TC1252E controller. The SOP-8 package saves PCB space and is the preferred solution for cost-sensitive projects. The switching frequency can be precisely set from 50 kHz to 500 KHZ through the ground resistance.
