The UCC28230DRNT is an integrated circuit (IC) component that belongs to the UCC282xx family of high-performance current-mode PWM controllers, designed for offline and low-voltage DC-DC converters. It offers several key features that enhance its performance and reliability.
One of the primary features of the UCC28230DRNT is its ability to operate under a wide input voltage range, making it suitable for a variety of applications. It can handle input voltages from 4.5V to 75V, enabling it to be used with different power supply systems.
This IC component incorporates a current-mode control topology, which facilitates excellent line and load regulation. A built-in error amplifier allows for precise voltage feedback regulation, ensuring stable and accurate conversion.
The UCC28230DRNT offers flexible options for the oscillator frequency, which can be easily adjusted using external resistors or capacitors. This flexibility provides designers the freedom to choose an optimal switching frequency that meets their specific requirements.
It also provides versatile protection features such as overvoltage protection (OVP), cycle-by-cycle current limit, and thermal shutdown. These protections guard the IC and connected components against potential faults, preserving the integrity of the system.
To further improve efficiency and simplify design, this IC component incorporates a low-current startup feature. This enables the converter to safely start up with minimal power dissipation, reducing overall energy wastage
