User Manual
Contents
This evaluation board user manual describes the 150 W
High Power Density Adapter and its main parameters like
efficiency, no−load input power consumption, EMI
signature, transient responses, etc. The evaluation board is
dedicated to present ON Semiconductor's high performance
controllers. High Power Density design is enabled when
using these controllers and higher switching frequency.
Higher efficiency can be achieved by using GaN HEMT
devices instead of Silicon Super−junction MOSFETs.
The evaluation board comprising of the PFC boost
converter operated in the critical conduction mode (CrCM)
and LLC power stage. The PFC front stage is driven by
NCP1615, assures unity power factor and low input current
THD. The LLC stage operates @ 260 to 300 kHz @ nominal
load and it's managed by the NCP1399 high performance
current mode LLC controller. Super−junction Si MOSFETs
(like FCMT199N60) can be assembled as primary side
power switches. The CV/CC controller NCP4353A ensures
output voltage regulation.
Above mentioned controllers are placed on the Control
Module. Secondary side utilizes synchronous rectifier (SR)
from NCP4305 or NCP4306 family composed with
NVMFS5C645NL 4mW 60V Power MOSFET. Whole SR
stage is implemented on the daughter card for easier main
power board PCB design. The discrete or integrated LLC
resonant thanks implementations can be used in one board
with few changes thanks to universal design.
