Key Features
- Wide 3.8 V to 30 V input range accommodates telecom 24 V and automotive 12 V rails
- Current-mode PWM control ensures fast transient response and inherent cycle-by-cycle current limiting
- Compact 8-pin WSON package (2 mm × 2 mm) minimizes PCB area for dense multi-rail designs
Applications
The TPS62932DRLR is designed for point-of-load step-down conversion in industrial automation, telecom line cards, and battery-powered portable equipment. Its wide input range and current-mode control make it well-suited for 24 V bus architectures requiring tightly regulated 3.3 V or 5 V downstream rails. The small WSON footprint also enables power delivery in space-restricted wearable and IoT modules.

Frequently Asked Questions
What input voltage range does TPS62932DRLR support, and how does that fit a 24 V telecom bus?
The TPS62932DRLR operates from 3.8 V to 30 V input, directly accommodating standard 24 V telecom bus rails without a pre-regulator. The 30 V maximum also provides margin for transients, and the 3.8 V minimum enables single-cell Li-ion battery use down to near-end-of-discharge.
How does the current-mode PWM control of TPS62932DRLR improve transient response compared to voltage-mode converters?
Current-mode control adds an inner current feedback loop that responds within one switching cycle, reducing output voltage deviation by 40-60% under fast load steps compared to voltage-mode designs. This means the TPS62932DRLR can maintain regulation within ±2% during 100 mA/µs load transients with standard output capacitor values.
What package does TPS62932DRLR use, and what land area does it occupy on a PCB?
The TPS62932DRLR comes in an 8-pin WSON package measuring approximately 2 mm × 2 mm, occupying just 4 mm² of PCB real estate. This ultra-compact footprint is well-suited for multi-rail designs on densely populated boards in IoT and wearable applications.
For a 5 V to 3.3 V, 500 mA point-of-load conversion, when should an engineer select TPS62932DRLR over a linear regulator?
When the 5 V to 3.3 V conversion carries 500 mA continuously, a linear regulator dissipates 850 mW of heat, requiring a large thermal pad or heatsink. The TPS62932DRLR switching regulator achieves greater than 90% efficiency at that operating point, cutting heat dissipation to under 85 mW and eliminating the thermal management overhead.
