ZHCSKA3D September 2019 – November 2023 UCC21750-Q1
PRODUCTION DATA
The design of the power system for end equipment must consider some design requirements to ensure the reliable operation of the UCC21750-Q1 through the load range. The design considerations include the peak source and sink current, power dissipation, overcurrent and short circuit protection, AIN-APWM function for analog signal sensing and so forth.
A design example for a half bridge based on IGBT is given in this subsection. Table 9-1 shows the design parameters.
