Frequently Asked Questions
What is the input voltage range of the UCC2808AD-1?
The UCC2808AD-1 operates with an input voltage range of 9V minimum to 14V maximum, with a nominal operating point of 10V. This makes it suitable for 12V bus power systems commonly found in telecom, industrial, and automotive applications.
What control mode does the UCC2808AD-1 use?
The UCC2808AD-1 uses current-mode pulse width modulation (PWM) control. Current-mode control provides inherent cycle-by-cycle overcurrent limiting, improved line rejection, and simplified loop compensation compared to voltage-mode controllers, making it ideal for high-reliability power supply designs.
What are the typical applications for the UCC2808AD-1?
Typical applications include isolated DC-DC converters for telecom and industrial equipment, half-bridge and full-bridge switching power supplies, motor drive pre-driver circuits, and battery charger systems. Its dual 1A outputs and 1MHz switching capability support compact, high-efficiency designs.
Is the UCC2808AD-1 available in other package options?
The UCC2808AD-1 is offered in an 8-pin SOIC (Small Outline IC) package with JESD-30 code R-PDSO-G8. Texas Instruments may offer functionally equivalent variants in different packages; consult the product family datasheet for alternative pin-compatible options such as DIP or TSSOP.
