Frequently Asked Questions
What control modes does the UCC28C41DGKRG4 support?
The UCC28C41DGKRG4 supports both voltage-mode and current-mode PWM control. The primary control technique is voltage-mode pulse-width modulation, with an additional feature enabling current-mode operation, giving designers flexibility to choose the most appropriate control strategy for their power topology.
What is the input voltage range of the UCC28C41DGKRG4?
The UCC28C41DGKRG4 operates with an input voltage range of 12V minimum to 18V maximum, with a nominal operating voltage of 15V. This range is typical for bias supply rails in isolated switching power supplies and multi-output DC-DC converter control stages.
What package does the UCC28C41DGKRG4 use and how many pins does it have?
The UCC28C41DGKRG4 is housed in an 8-pin Very Thin Small Outline Package (VSSOP), JESD-30 code S-PDSO-G8. This compact surface-mount package is ideal for designs requiring a small controller footprint without sacrificing the full feature set of the UCC28C41 controller family.
What switching topologies is the UCC28C41DGKRG4 suitable for?
This PWM controller is designed for use in multiple power supply topologies including flyback converters, forward converters, and push-pull converters. Its voltage-mode PWM with current-mode capability makes it adaptable to single-ended and double-ended isolated power supply designs commonly found in industrial and telecom equipment.
Is the UCC28C41DGKRG4 RoHS compliant?
The UCC28C41DGKRG4 has a Pb-free code listed as 'No' in its specifications, indicating this specific variant may not be fully RoHS compliant. Designers requiring lead-free and RoHS-compliant parts should verify the current compliance status with Texas Instruments or the distributor before use in regulated applications.
