Key Features
- 3 V to 6 V input synchronous buck regulator with output voltage tracking for sequenced power-up of multi-rail FPGA and DSP systems
- Voltage-mode PWM control with external compensation allows optimization of transient response for loads requiring less than 50 mV output deviation
- Enhanced-product qualification (EP suffix) provides extended operating life screening suitable for automotive, defense, and long-lifecycle industrial designs
Applications
TPS54680QPWPREP powers core and I/O voltage rails in FPGA, DSP, and processor SoC designs that require precise power sequencing and output voltage tracking from a 3 V to 6 V bus. Its enhanced-product screening makes it appropriate for automotive ADAS controllers, avionics power management boards, and industrial PLCs with 10-year to 20-year service life requirements. The synchronous rectification topology improves efficiency above 90% at moderate load currents, benefiting thermal-constrained enclosures.

Frequently Asked Questions
How does the output voltage tracking feature of TPS54680QPWPREP benefit FPGA power sequencing?
TPS54680QPWPREP's tracking pin allows its output to ramp in proportion to a reference rail, ensuring the FPGA core voltage reaches its target within 5 ms of the I/O supply, preventing latch-up conditions. Most FPGAs specify that the core rail must remain within 300 mV of the I/O rail during power-up, a requirement the tracking function meets automatically without external sequencing ICs or microcontroller intervention.
What switching frequency range suits TPS54680QPWPREP in a 3.3 V to 1.8 V conversion for a processor board?
TPS54680QPWPREP supports programmable switching frequencies typically between 200 kHz and 600 kHz via an external resistor on the RT/CLK pin. For a 3.3 V input to 1.8 V output conversion supplying a processor core at up to 6 A, a 300 kHz to 400 kHz setting balances inductor size (typically 1.5 µH to 3.3 µH) against switching losses, achieving conversion efficiency above 92% at 3 A load.
When does the enhanced-product (EP) qualification of TPS54680QPWPREP justify its cost premium over the standard TPS54680?
TPS54680QPWPREP's enhanced-product qualification includes extended burn-in screening and additional electrical characterization across -40°C to +125°C, making it the preferred choice when the end product must meet IATF 16949 automotive quality requirements or MIL-HDBK-217 reliability targets. In designs with 15-year field service goals and fewer than 10 FIT (failures in 10⁹ device-hours) budgets, the EP screening provides confidence that standard-grade parts cannot offer at production volumes.
