About the Product

Efficient Replacement Part for Avalon A1346 Power Supply

Upgrade and enhance the performance of your Avalon A1346 power supply PSU3400-03 with the UCC28C45DR high-performance PWM controller. Designed for lower power consumption and improved efficiency, this controller offers faster current sensing, precise oscillation frequency, and essential functionalities for controlling fixed-frequency, peak-current-mode power supplies.

UCC28C45DR High-Performance PWM Controller for Improved Power Efficiency

The UCC28C45DR operates at a maximum frequency of 1 MHz, ensuring optimal power conversion. With a startup current of 50μA (maximum 100μA), it minimizes power requirements during system initialization. The low operating current of 2.3 mA at a frequency of 52 kHz further enhances energy efficiency.

Featuring fast cycle-by-cycle overcurrent limiting with a response time of 35ns, the UCC28C45DR provides excellent overload protection for the power switch, ensuring reliable operation. With a peak driving current of ±1A and an accurate 2.5V error amplifier reference with ±1% accuracy, it guarantees precise control and regulation of the power supply.
