Frequently Asked Questions
What control mode does the UCC3888NG4 use for switching regulation?
The UCC3888NG4 uses voltage-mode control, where the output voltage is sensed and compared to a reference to adjust the duty cycle of the switching signal. This simplifies the compensation network design compared to current-mode controllers and provides stable regulation over line and load variations.
What are the input and output voltage specifications of the UCC3888NG4?
The UCC3888NG4 operates from a minimum input voltage of 6.6 V with a nominal input of 9 V, producing a nominal output voltage of 5 V. The maximum output current is 200 mA, making it suitable for low-power auxiliary supply rails and point-of-load applications.
What package does the UCC3888NG4 use and is it RoHS compliant?
The UCC3888NG4 is housed in an 8-pin PDIP (JESD-30 code R-PDIP-T8) through-hole package, ideal for prototype boards and legacy designs. Note that the Pb-free code for this specific part number is No, indicating it uses leaded solder finish — confirm compliance requirements before use in restricted applications.
What are typical applications for the UCC3888NG4?
Typical applications include DC-DC buck converters, flyback regulators, and auxiliary power supply stages in industrial control systems, telecommunications equipment, and embedded power modules requiring a simple, stable 5 V regulated output from a 9 V supply bus.
