Key Features
- Current-mode PWM control with cycle-by-cycle current limiting provides inherent over-current protection and fast transient response in boost and flyback topologies
- Narrow input voltage range of 9V to 12V (nominal 10V) optimizes the controller for telecom and industrial 10V bus architectures
- 8-pin SOIC package with industry-standard pinout simplifies drop-in replacement and PCB layout in high-volume switching power supply designs
Applications
The UCC2802DTRG4 is widely used as the control core in isolated flyback and non-isolated boost power supplies for telecom equipment, industrial instrumentation, and distributed power systems operating from a 10V intermediate bus. Its current-mode control architecture makes it straightforward to design stable, fast-responding converters with good line and load regulation. The device is also suitable for auxiliary supply designs in motor drives and UPS systems where a compact, reliable PWM controller is required.

Frequently Asked Questions
What control mode does the UCC2802DTRG4 use and why does it matter?
It uses current-mode PWM control, which provides inherent cycle-by-cycle over-current limiting, improved line rejection, and simpler loop compensation compared to voltage-mode control, resulting in more robust and faster-responding power supply designs.
What input voltage range does the UCC2802DTRG4 support?
The UCC2802DTRG4 operates with an input voltage between 9V minimum and 12V maximum, with a nominal operating voltage of 10V, making it specifically suited for 10V intermediate bus architectures common in telecom and industrial applications.
What topologies can the UCC2802DTRG4 control?
It is designed primarily for boost and flyback converter topologies, covering both isolated and non-isolated power supply designs, and can be used in auxiliary, off-line, or distributed power supply applications.
Is the UCC2802DTRG4 RoHS compliant?
The UCC2802DTRG4 carries a JESD-609 code of e4, indicating it is a lead-free and RoHS-compliant device, though the Pbfree code field also lists it as available in both lead-free and leaded variants depending on the specific ordering suffix.
