UCC25800BQDGNRQ1 - Ultra-low EMI Transformer Driver for Isolated Bias Supplies

Part Number: UCC25800BQDGNRQ1

Package: HVSSOP-8

Type:  Professional Power Management - EMI Transformer Driver

Product Overviews

UCC25800BQDGNRQ1 is ultra-low EMI transformer driver, it integrates the switching power stage, the control, and the protection circuits to simplify isolated bias supply designs. It allows the design to utilize a transformer with higher leakage inductance, but much smaller parasitic primary-to-secondary capacitance. This low-capacitance transformer design enables an order of magnitude reduction in the common-mode current injection through the bias transformer. 

UCC25800-Q1 - Key Features

• High-efficiency half-bridge transformer driver

• Ultra-low EMI with low interwinding capacitance

• Smaller and lower-cost transformer

– Programmable frequency: 0.1 MHz to 1.2 MHz

• Wide input voltage range: 9 V to 34 V

• External clock synchronization for low noise

• Robust protection features

– Undervoltage lockout (UVLO)

– Programmable over-current protection (OCP)

– Input overvoltage protection (OVP)

– Over temperature protection (TSD)

– Integrated soft-start to reduce in-rush current

– External disable function with fault-code output

UCC25800-Q1 - Simplified Application:

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
