STMicroelectronics L6928D013TR: High-Efficiency DC-DC Converter

The L6928D013TR from STMicroelectronics is a highly efficient, monolithic synchronous step-down DC-DC converter that is designed to deliver a stable and reliable power supply in a variety of electronic applications. This integrated circuit (IC) features a wide input voltage range, making it suitable for use in systems powered by a Li-ion battery, a multi-cell battery pack, or a regulated power supply.

With its advanced high-switching frequency, the L6928D013TR achieves excellent power conversion efficiency while minimizing the size of external components. This characteristic makes it an ideal solution for space-constrained applications such as portable devices, wearables, and IoT endpoints. The device operates at a fixed frequency of 1.5MHz, allowing for the use of small surface-mount inductors and capacitors, which contribute to a reduced overall footprint on the PCB.

The L6928D013TR incorporates a range of features to ensure the protection and longevity of the end application. These include under-voltage lockout (UVLO), thermal shutdown, and over-current protection (OCP). The UVLO function ensures that the device operates only when the input voltage is within a safe range, while thermal shutdown prevents damage due to excessive heat, and OCP safeguards the IC against short-circuit conditions.

For design flexibility, the L6928D013TR provides an adjustable output voltage from 0.6V to VIN, allowing designers to tailor the output to meet specific requirements. Additionally, the device offers a Power Good (PG) output that can be used for power sequencing or as an indicator that the output voltage is within regulation.

The L6928D013TR is available in a compact QFN-16 package, which is ideal for modern, high-density circuit designs. This product is part of STMicroelectronics' commitment to providing energy-efficient power solutions that extend battery life and reduce the environmental impact of electronic devices.

Whether it's for mobile phones, personal media players, or complex digital systems, the L6928D013TR is a reliable choice for designers looking to optimize power management in their next-generation electronic products.
