TPS54302DDC – TEXAS INSTRUMENTS

The TPS54302DDC is a 2A synchronous step-down converter from Texas Instruments, packaged in a compact 16-pin QFN (4x4mm) package. It operates from a wide input voltage range of 4.5V to 18V, delivering a precisely regulated output voltage adjustable from 0.8V to 5.5V. This device utilizes internal high-side and low-side MOSFETs, eliminating the need for external Schottky diodes, simplifying design and reducing component count. Its internal compensation network minimizes external component requirements, further streamlining the design process. The TPS54302DDC features a switching frequency of 1.2MHz, enabling the use of smaller, less expensive inductors and output capacitors._x000D_

Key features include an adjustable output voltage via a single resistor, a 100% duty cycle mode for improved light-load efficiency, and integrated protection mechanisms such as overcurrent, overtemperature, and short-circuit protection. Its high efficiency, typically exceeding 90% across its operating range, makes it ideal for applications requiring high power density and low thermal dissipation, such as portable devices, industrial control systems, and point-of-load converters in high-performance computing applications where space and efficiency are paramount. The device’s small form factor and robust protection features contribute to its suitability for demanding environments.
