FAQs
What is TPS62903RPJR?
The TPS62903RPJR is a synchronous step-down DC-DC converter from Texas Instruments. It is designed for high efficiency power conversion in battery-powered applications, IoT devices, portable electronics, and other low-power systems.
How Does TPS62903RPJR Work?
The TPS62903RPJR operates by converting a higher input voltage to a lower output voltage with high efficiency. It utilizes a synchronous buck topology to regulate the output voltage, providing a stable power supply for electronic devices. The converter features a pulse-width modulation (PWM) control scheme and low-dropout mode for improved power efficiency.
How Many Pins does TPS62903RPJR have and What are the Functions of the Pinout Configuration?
The TPS62903RPJR is packaged in a compact 10-pin VQFN (Very Thin Quad Flat No-Lead) package. The pinout configuration includes:
- VIN: Input voltage pin.
- EN: Enable pin for turning the converter on/off.
- PGND: Power ground pin.
- SW: Switch node for inductor connection.
- FB: Feedback pin for output voltage regulation.
- AGND: Analog ground pin.
- SS/TR: Soft-start or tracking pin for output voltage ramp control.
- PGOOD: Power-good indicator output pin.
- LX: Inductor connection pin.
- VOUT: Output voltage pin.
What are the Pros and Cons of TPS62903RPJR?
Pros:
- High Efficiency: Provides high efficiency power conversion for extended battery life.
- Compact Size: Compact 10-pin VQFN package for space-constrained designs.
- Low Dropout Mode: Enables operation with low input-output voltage differentials.
- Adjustable Soft-Start: Soft-start feature for controlled output voltage ramp-up.
- Power-Good Indicator: Includes a power-good indicator for system monitoring.
Cons:
- Complexity: Synchronous buck converters may require careful consideration of layout and component selection.
- Temperature Sensitivity: Performance may be affected by temperature variations in some operating conditions.
- External Components: Additional external components may be needed for specific applications.
Are There Any Equivalents/Alternatives to TPS62903RPJR for Recommendation?
- The TPS62823 from Texas Instruments offers similar synchronous buck converter features in a different package.
