UC2825AMDWREP

The UC2825A-EP PWM controller represents a significant advancement over the standard UC2825, with performance enhancements and functional improvements that make it an ideal choice for demanding electronic applications. The controller boasts an error amplifier gain bandwidth product of 12 MHz and an input offset voltage of just 2 mV, ensuring precision and accuracy in operation. With a current-limit threshold specified to a tolerance of 5% and an oscillator discharge current of 10 mA for accurate dead-time control, the UC2825A-EP delivers reliable performance in a wide range of scenarios. Furthermore, the redesigned output drivers actively sink current during undervoltage lockout (UVLO), while each output is capable of 2-A peak currents during transitions, highlighting the controller's versatility and robustness. The UC2825A-EP also features functional improvements, including a high-speed overcurrent comparator with a threshold of 1.2 V and dual alternating outputs, as well as the same pin configuration as the original UC2825. For detailed technical and application information, users can refer to the application report, The UC3823A,B and UC2825A,B Enhanced Generation of PWM Controllers, literature number SLUA125, which provides comprehensive insights into the capabilities of the UC2825A-EP PWM controller
