Frequently Asked Questions
What input voltage range does the UCC256402DDBR support for LLC resonant converter designs?
The UCC256402DDBR supports an input voltage range of 13 V to 30 V, with a nominal input voltage of 15 V. This 13 V to 30 V range makes it suitable for a broad set of AC/DC power supply topologies including LLC resonant and flyback converters requiring regulated gate drive and housekeeping power.
In which package is the UCC256402DDBR supplied and how does it affect thermal management on a PCB?
The UCC256402DDBR is supplied in a 14-pin SOIC package with a body width of approximately 3.9 mm, enabling compact PCB placement. The SOIC footprint provides adequate copper area for heat spreading, and when paired with proper ground planes, it supports continuous operation across the -40°C to +125°C junction temperature range specified by Texas Instruments.
When is UCC256402DDBR a preferred alternative to a PWM controller in an AC/DC design?
UCC256402DDBR is the preferred alternative when the design demands resonant LLC operation to achieve zero-voltage switching, reducing switching losses at frequencies above 100 kHz. Compared to fixed-frequency PWM controllers, its resonant control technique lowers EMI, improves efficiency by 2% to 4%, and eliminates the need for large snubber networks, saving board space and BOM cost.
