Frequently Asked Questions
What control modes does the UCC39422NG4 support?
The UCC39422NG4 supports voltage-mode PWM control as its primary regulation architecture. Additionally, it offers configurable peak current mode and a programmable PFM (Pulse Frequency Modulation) technique, enabling the designer to optimize efficiency for both heavy-load and light-load operating conditions.
What is the input voltage range of the UCC39422NG4?
The UCC39422NG4 operates over an input voltage range of 1.8V minimum to 8V maximum, with a nominal design voltage of 3V. This range makes it directly compatible with single-cell lithium-ion batteries, two-cell alkaline batteries, and regulated 3.3V or 5V system rails.
What package does the UCC39422NG4 use?
The UCC39422NG4 is packaged in a 20-pin PDIP (Plastic Dual-In-Line Package), which uses through-hole leads on 0.1-inch centers. This package is easy to hand-solder and works directly in IC sockets, making it popular for prototyping, lab evaluation, and educational power electronics projects.
Is the UCC39422NG4 RoHS compliant?
The UCC39422NG4 carries a Pb-free code of No, meaning this specific variant is not lead-free and is not RoHS compliant. Designers working on products requiring RoHS compliance should check for an alternative lead-free version or confirm the regulatory status with their distributor before designing it in.
