3 Description

The UCC5304 device is an isolated single-channel

gate driver with 4-A peak-source and 6-A peak-sink

current. It is designed to drive power MOSFETs and

GaNFETs in PFC, Isolated AC/DC, DC/DC, and

synchronous rectification applications, with fast

switching performance and robust ground bounce

protection through greater than 100-V/ns commonmode

transient immunity (CMTI).

The UCC5304 is available in a 8.5 mm SOIC-8

(DWV) package and can support isolation voltage up

to 5-kVRMS. Compared to an optocoupler, the

UCC5304 family has lower part-to-part skew, lower

propagation delay, higher operating temperature, and

higher CMTI.

Protection features include: IN pin rejects input

transient shorter than 5-ns; both input and output can

withstand –2-V spikes for 200-ns, both supplies have

undervoltage lockout (UVLO), and active pull down

protection clamps the output below 2.1-V when

unpowered or floated.

With these features, this device enables high

efficiency, high power density, and robustness in a

wide variety of power applications.
