What should engineers review before using UCC25800AQDGNQ1?

Review the 9 V to 34 V fixed-input requirement, transformer turns ratio and leakage inductance, resonant capacitors, 100 kHz to 1.2 MHz switching setting, OC/DT divider, thermal layout, and VCC-to-GND bypass loop.

What is the pinout of UCC25800AQDGNQ1?

Use the UCC25800AQDGNQ1 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about UCC25800AQDGNQ1 pinout to locate pins, power rails, and interface signals before layout.

AI summary

UCC25800AQDGNQ1 is an automotive-qualified integrated half-bridge transformer driver for fixed-input, isolated LLC bias supplies requiring low EMI and low transformer interwinding capacitance.

Best for

Automotive isolated gate-driver bias supplies
Low-EMI LLC bias converters
SiC, IGBT, and GaN driver bias rails

Avoid if

A tightly regulated output is required without post-regulation
The input supply voltage varies substantially
A topology other than an open-loop half bridge is required

Check before use

Verify transformer isolation, creepage, and parasitic capacitance requirements
Set OCP for the intended load rather than using the highest setting by default
Validate soft switching and adaptive dead-time at load and temperature extremes
