Frequently Asked Questions
What is the UCC38051DG4 and what is its primary function?
The UCC38051DG4 is a current-mode power factor correction and PWM controller IC from Texas Instruments. It is designed to improve the power factor of AC-DC switching power supplies by shaping the input current waveform to follow the AC line voltage. It operates with an input voltage range of 10V to 18V and supports switching frequencies up to 200kHz.
What are the key electrical specifications of the UCC38051DG4?
The UCC38051DG4 operates from 10V minimum to 18V maximum input voltage, with a nominal operating voltage of 12V. It supports PWM switching frequencies up to 200kHz using current-mode control. The device is packaged in an 8-pin SOIC (JESD-30 code R-PDSO-G8) and is rated as lead-free with JESD-609 e4 designation, making it suitable for RoHS-compliant designs.
What package and supply format does the UCC38051DG4 use?
The UCC38051DG4 is available in an 8-pin SOIC (Small Outline Integrated Circuit) package. The G4 suffix in the part number indicates it is supplied in tube packaging, which is suitable for prototype and low-to-medium volume production. For high-volume tape-and-reel supply, other package variants of the UCC38051 family may be available.
What applications is the UCC38051DG4 designed for?
The UCC38051DG4 is designed for use in active power factor correction circuits for offline AC-DC power supplies, including server power supplies, industrial power converters, and energy-efficient lighting systems. Its current-mode PWM control enables compliance with IEC 61000-3-2 harmonic emission standards. It is also suitable for front-end boost converters in telecom and UPS applications.
Is there a difference between the UCC38051DG4 and other UCC38051 variants?
Yes, the UCC38051DG4 uses the D suffix denoting an SOIC package and G4 indicating tube packaging. Other variants in the UCC38051 family may differ in package type (such as SOIC with different pin counts), supply format (tape and reel vs tube), or environmental ratings. Always verify the package and supply format by checking the Texas Instruments datasheet and part number suffix guide before ordering.
