FAQs
What is TPS54521RHLR?
The TPS54521RHLR is a high-efficiency, synchronous step-down DC-DC converter designed by Texas Instruments. It is well-suited for applications requiring a compact and efficient power supply solution, such as telecom, industrial, and consumer electronics.
How Does TPS54521RHLR Work?
The TPS54521RHLR operates as a step-down converter, efficiently reducing a higher input voltage to a lower output voltage. It utilizes synchronous rectification for higher efficiency and features a pulse-width modulation (PWM) control loop for accurate voltage regulation. The converter is capable of delivering high currents while maintaining high efficiency.
How Many Pins does TPS54521RHLR have and What are the Functions of the Pinout Configuration?
The TPS54521RHLR is housed in a 16-pin QFN (Quad Flat No-leads) package. The pinout configuration includes:
- VIN: Input voltage pin.
- BOOT: Bootstrap capacitor pin for the high-side MOSFET driver.
- PGND: Power ground pin.
- SW: Switching node for the inductor connection.
- FB: Feedback input for the output voltage regulation.
- SS/TR: Soft-start/tracking pin for setting the start-up time.
- EN: Enable pin for turning the converter on and off.
- COMP: Compensation pin for loop stability.
- SS/TR: Soft-start/tracking pin for setting the start-up time.
- PGND: Power ground pin.
