TPS2003CDRCR – TEXAS INSTRUMENTS

The TPS2003CDRCR is a Texas Instruments single-channel, 3A synchronous buck converter in a compact 6-pin SOT-23-6 package. It features a wide input voltage range of 2.7V to 5.5V, enabling operation from a variety of power sources. The device boasts a high efficiency exceeding 90% at typical operating currents, minimizing power loss and heat generation. Output voltage is adjustable via an external resistor divider, allowing for flexible design choices within the device’s 0.8V to V_IN range. Its internal 3A switch and integrated MOSFETs simplify design and reduce component count compared to discrete solutions._x000D_

The TPS2003CDRCR incorporates features like soft-start and overcurrent protection, enhancing system stability and reliability. Its small size and low profile make it ideal for space-constrained applications in portable devices, battery-powered equipment, and other power-sensitive designs. Common use cases include powering low-voltage digital circuits, powering sensor nodes, and voltage regulation in small form-factor systems. The device’s efficiency advantage translates to longer battery life in portable applications and reduced thermal management requirements in general. However, its 3A current limit restricts its use to lower-power applications. Careful consideration of the output voltage range and thermal dissipation is necessary for optimal performance.
