Today, electronic products are getting smaller and require more power in less size. This has driven the demand for higher power density and higher efficiency DC-DC converters and power supplies. The UTPSP20GYY is a DC-DC converter that meets the high performance requirements of embedded applications in consumer, medical and industrial markets. The product offers superior power density, very high efficiency and a wide input voltage range of 4.75V to 28V.

The UTPSP20GYY is a high-performance, non-isolated synchronous step-down converter in a compact, thermally enhanced 4mm x 4mm QFN package. It is an ideal solution for power management applications such as laptops, tablets, industrial automation, and medical equipment. The product offers an output voltage range of 0.6V to 17V with programmable output current of up to 2A and includes a full set of features to manage output voltage regulation, current limiting, over-temperature protection, remote sensing, and enhanced shutdown. It also has an internal compensation network for stable and precise output voltage regulation.

The device also comes with an integrated, low-loss, low-noise power stage optimized for best efficiency and power density. The high efficiency of the device is a key feature since it helps to minimize power loss due to thermal impact. The high efficiency of up to 97% and the integrated power stage simplify the design-in process and reduce the system development time.

The UTPSP20GYY operating principle is based on pulse-width modulation (PWM) technique. This controlled PWM modulates the average value of the output voltage, thus regulating the output voltage. The PWM pulses are generated using a PWM controller IC, which leads to a wide range of applications including on/off control, dimming, and speed control.

The UTPSP20GYY offers various protection features such as current limit, over-temperature protection, and short-circuit protection. To ensure robustness, the power module is certified to meet various environmental standards including lead-free RoHS, WEEE, and REACH. Furthermore, the operating ambient temperature range is -40°C to +85°C.

In summary, the UTPSP20GYY power module is a high-performance, cost-effective solution for embedded consumer, medical, and industrial applications. It offers superior power density, very high efficiency, and wide input voltage range with various system protection features. The integrated power stage and the low-noise, high-efficiency design make it a perfect choice for space-constrained applications in highly regulated environments.
