PRODUCTION DATA
The UCC28C5x-Q1 controllers are peak current mode pulse width modulators. These controllers have an integrated error amplifier and can be used in isolated or nonisolated power supply designs. There is an on-chip gate driver capable of delivering 1 A of peak current. This is a high-speed PWM capable of operating at switching frequencies up to 1 MHz. Figure 9-1 shows a typical high-voltage input application with UCC28C56H-Q1.
