TPS54680PWPR

TPS54680PWPR is TI’s high-efficiency buck regulator from the SIMPLE SWITCHER family. It accepts a wide input voltage (suitable for automotive/industrial use) and produces a regulated output via a switching integrated MOSFET. External components needed include an inductor, input/output capacitors, and a feedback network to set Vout. Key features typically include enable/shutdown, soft-start, overcurrent and thermal protection, undervoltage lockout, and fault protection. It is offered in the PWPR package for compact boards. Applications include automotive and industrial power rails and other embedded-system power supplies. Design requires selecting an appropriate inductor and capacitors and following TI’s reference designs and layout guidelines for stability and EMI. For exact input range, output options, current capability, switching frequency, and pinout, consult the TPS54680PWPR datasheet and product page.

Do you need TI cross-references (same family) or third-party equivalents? Please provide: input voltage range, desired output voltage/current, switching frequency, and package. With that, I’ll give exact equivalent part numbers.

Here are the key features of the TPS54680PWPR (high-level):
- High-efficiency step-down (buck) regulator with integrated high-side and low-side MOSFETs (synchronous rectification)
- Wide input voltage range for automotive/industrial applications
- Adjustable output voltage via external feedback divider (with optional remote sensing)
- Enable input and Power-Good (PG) signal for sequencing and monitoring
- Internal soft-start and controlled output ramp
- Protection features: overcurrent/short-circuit protection, over/undervoltage lockout, and thermal shutdown
- Robust transient and fault handling suitable for harsh environments
- Fixed-frequency PWM operation with compact PWPR package (offers good thermal performance)
- Low quiescent current and suitability for compact, multi-rail designs
Note: For exact electrical specs (voltage ranges, supported outputs, switching frequency, current capability), please refer to the data sheet.

Pin count: 8 pins.
Function: TPS54680PWPR is a high‑efficiency synchronous buck (step-down) DC‑DC regulator. It converts a higher input voltage to a regulated lower output and includes enable control, feedback for regulation, soft-start, and bootstrap circuitry to drive the high‑side switch.
