Applications
The UCC25705DGKTR is designed for high-frequency voltage-mode PWM control in compact switch-mode power supplies, resonant converters, and DC/DC regulators where small magnetics and high power density are priorities. Its 1100kHz maximum switching capability makes it well-suited for point-of-load converters in telecommunications, industrial automation, and server power systems requiring fast transient response and tight voltage regulation. The 8-pin VSSOP package minimizes PCB real estate, making it ideal for power module designs and embedded power management circuits where board space is at a premium.

Frequently Asked Questions
What is the maximum switching frequency supported by the UCC25705DGKTR?
The UCC25705DGKTR supports a maximum switching frequency of 1100kHz (1.1MHz), enabling the use of smaller inductors and capacitors in power supply designs. This high-frequency capability is particularly valuable in compact DC/DC converters and resonant power supplies where reducing the size of passive components is a key design goal.
What is the input voltage range for the UCC25705DGKTR?
The UCC25705DGKTR operates with an input voltage range from 9V minimum to 15V maximum, with a nominal supply of 11V. This range is compatible with regulated 12V power rails common in industrial, telecommunications, and server power distribution systems, making it a convenient controller for secondary-side regulation and point-of-load power designs.
What package does the UCC25705DGKTR use and how does it benefit PCB layout?
The UCC25705DGKTR comes in an 8-pin VSSOP (S-PDSO-G8) package, a very small surface-mount outline that minimizes PCB footprint. This compact package simplifies PCB layout in power modules, adapter boards, and embedded power circuits where multiple functions must be packed into a limited board area without sacrificing thermal or electrical performance.
Is the UCC25705DGKTR suitable for long-term production use?
Yes, the UCC25705DGKTR has a YTEOL (Years to End of Life) rating of 15 years and is manufactured with RoHS-compliant Pb-free materials per JESD-609 e4. This long product lifecycle and environmental compliance make it a reliable choice for designs requiring stable component sourcing over extended production runs in industrial and commercial applications.
