The Texas Instruments TPS63051RMWT is an ultra‑efficient, single‑inductor buck‑boost DC/DC converter designed for battery‑powered electronics demanding reliable operation across fluctuating voltages. With seamless switching between buck and boost modes, this compact (12-pin VQFN-HR) power management IC delivers a stable 3.3 V output of up to 500 mA, while drawing minimal quiescent current. Ideal for smartphones, IoT devices, smart meters, and other compact systems, the TPS63051RMWT ensures both peak performance and exceptional battery life even when the input voltage rises above or dips below the output.

Why Buy the TPS63051RMWT?

Choosing the TPS63051RMWT means investing in a versatile, cost‑efficient, and power‑savvy solution for your DC/DC conversion needs. It stands out by delivering high efficiency (>95% in buck mode, >90% in boost mode), ultra-low standby current, and adaptive performance across a wide input voltage range (2.5V to 5.5V). Whether your project involves a portable device or a low-power IoT sensor, this regulator provides stability, flexibility, and energy savings in a compact package.

Product Highlights – What Makes It Stand Out

Seamless Buck‑Boost Regulation — Automatically transitions between buck and boost modes to maintain a stable output regardless of input voltage fluctuations.
Wide Input Voltage Window — Operates reliably across a 2.5 V to 5.5 V input range, covering many battery and supply scenarios.
Strong Output Capability — Delivers up to 500 mA continuous in boost mode; up to 1 A in buck mode.
Top-Tier Efficiency — Achieves >90% in boost and >95% in buck operation, reducing wasted energy and heat.
Low Quiescent Power Drain — Operates with a device quiescent current of under 60 µA, optimising battery life during idle periods.
Fast Switching (2.5 MHz) — High-frequency switching enables the use of smaller external components, thereby minimising the overall design footprint.
Soft-Start & Input Current Control — Includes adjustable soft‑start and average input current limit to safeguard components and prevent inrush spikes.
Flexible Mode Control — The PFM/PWM pin allows users to toggle between power-save (PFM) and forced PWM modes for efficiency-versus-noise optimisation.
Load Isolation During Shutdown — Fully disconnects output in shutdown mode, preventing parasitic current draw.
Built-In Thermal Safety — Includes over-temperature protection to ensure safe and robust system operation.
