Texas Instruments TPS62175DQCT Adjustable Buck DC-DC Converter, WSON-10, 500mA

The Texas Instruments TPS62175DQCT is a high-efficiency, synchronous step-down DC/DC converter based on the advanced DCS-Control™ topology. Designed for reliability and performance, it operates from a wide input voltage range of 4.75V to 28V, making it perfectly suited for systems powered by multi-cell Li-ion batteries, 12V rails, or even higher intermediate supply lines, delivering a robust output current of up to 500mA.

A key feature is its intelligent power management. The device automatically enters a power save mode under light load conditions to maintain exceptional efficiency across the entire load spectrum. For applications requiring advanced power saving, such as those using ultra-low-power microcontrollers, it offers a dedicated sleep mode, reducing typical quiescent current to just 4.8µA. In this mode, efficiency at very low load currents can be improved by as much as 20%. A power good output signal is provided for reliable power sequencing and power-on reset functions.

Robust Protection and Features

Engineered for stability, the converter includes comprehensive protection mechanisms such as under-voltage lockout, short-circuit protection, and over-temperature protection to safeguard your circuitry. It supports a 100% duty cycle mode for lowest dropout operation and features active output discharge in shutdown mode, where the shutdown current is less than 2µA. The seamless transition between power modes ensures smooth operation without performance hiccups.

The device is presented in a compact, surface-mount WSON-10 package, ideal for space-constrained applications. It is a green product, manufactured without antimony or bromine-based flame retardants (no Sb/Br), aligning with modern environmental standards. Note: This device has limited built-in ESD protection; during storage and handling, leads should be shorted together or the device placed in conductive foam to prevent electrostatic damage to the
