Frequently Asked Questions
What switching topology is the UCC3895PWG4 designed for?
The UCC3895PWG4 is optimized for phase-shift full-bridge (PSFB) switching topology, which achieves zero-voltage switching (ZVS) across all four switches. This topology is widely used in high-power isolated DC-DC converters for server power supplies, telecom equipment, and industrial motor drives.
What is the maximum switching frequency of the UCC3895PWG4?
The UCC3895PWG4 supports switching frequencies up to 1000 kHz (1 MHz), enabling designers to use smaller transformer cores, inductors, and filter capacitors. Higher switching frequency reduces the physical size and weight of the power converter while maintaining tight voltage regulation.
Does the UCC3895PWG4 support current-mode control?
Yes, the UCC3895PWG4 supports both voltage-mode and current-mode PWM control, giving designers flexibility in their converter design approach. Current-mode control offers inherent cycle-by-cycle current limiting and improved transient response, while voltage-mode control simplifies compensation design.
What package is the UCC3895PWG4 available in?
The UCC3895PWG4 comes in a 20-pin TSSOP (Thin Shrink Small Outline Package) surface-mount package. The TSSOP-20 form factor offers a compact footprint suitable for high-density power supply PCB designs while providing adequate thermal dissipation for controller-level power dissipation.
