Frequently Asked Questions
How much output current can the TPS54327DDA supply continuously?
The TPS54327DDA supports up to 3A continuous output current. Both the high-side and low-side switching MOSFETs are integrated on-chip, eliminating the need for external FETs and reducing BOM cost.
What input voltage range does the TPS54327DDA support?
The device accepts an input voltage from 3.5V to 17V, making it compatible with standard 5V and 12V power rails common in industrial and embedded applications.
Which package does the TPS54327DDA use, and how many pins does it have?
The TPS54327DDA comes in a 10-pin HVSSOP (DDA) package with an exposed PowerPAD underneath, providing low thermal resistance and enabling reliable operation at full 3A load in typical PCB conditions.
Can the TPS54327DDA replace the TPS54320DDA?
Yes. The TPS54327DDA is pin-compatible with the TPS54320DDA and shares the same HVSSOP-10 footprint. The key difference is the fixed 2.977MHz switching frequency versus the adjustable frequency on the TPS54320, which affects filter component selection.
Is the TPS54327DDA RoHS compliant and what is the operating temperature range?
Yes, the TPS54327DDA is RoHS-compliant and lead-free. Its operating temperature range is -40°C to +85°C, suitable for both commercial and industrial environments.
