UCC25660x Half Bridge LLC Evaluation Module
Description
The UCC25660EVM-064 assists designers to
evaluate the operation and performance of the
UCC25660x LLC Resonant controller (16-pin SOIC
package with removed pins for high voltage
clearance). This evaluation module demonstrates how
UCC25660x controls the LLC resonant half bridge
DC-DC converter to achieve high effciency through
out the load and input voltage range.
Features
IPPC controlled (Input power proportional
control) LLC resonant half-bridge DC-DC power
conversion
DC line input from 365 VDC to 410 VDC
AC input voltage from 85 VDC to 265 VAC
Regulated 12-VDC typical output
Full-load power of 180 W, or full-load current of 15
A
High efficiency
Enhanced light load management:
– High frequency pulse skip for improved light
load efficiency
– Low frequency burst for reduced standby power
– Audible frequency range skip for reduced
audible noise
