Frequently Asked Questions
What is the input voltage range of the UCC3585D?
The UCC3585D operates with an input voltage range of 3 V to 5.5 V, with a nominal supply of 3.3 V. This makes it ideally suited for point-of-load buck converters powered directly from 3.3 V or 5 V system bus rails in digital computing and telecommunications equipment.
What control technique does the UCC3585D use?
The UCC3585D uses voltage-mode pulse width modulation (PWM) control. Voltage-mode control provides a fixed switching frequency and simplifies the compensation network design, making it a popular choice for synchronous buck converters with well-defined output voltage and load current requirements.
What package does the UCC3585D come in?
The UCC3585D is housed in a 16-pin SOIC surface-mount package, designated R-PDSO-G16. The SOIC format is compatible with standard automated SMT assembly processes and is widely available from Texas Instruments authorized distributors. Its compact footprint suits high-density PCB layouts in server and networking power supply designs.
Is the UCC3585D still in production and RoHS compliant?
Yes, the UCC3585D is Pb-free (lead-free) and carries a YTEOL value of 15, indicating it is an actively manufactured product with long-term availability. Introduced in November 1999, it remains a well-established and reliable choice for voltage-mode buck converter designs requiring RoHS-compliant components.
