Vue d'ensemble
Description
Key features include a fixed-frequency operation at 700 kHz, which ensures a compact design with smaller external components. It also has an adjustable output voltage via an external resistor divider, allowing for flexibility in different applications. The TPS54239DDAR integrates protection features such as current limit, thermal shutdown, and undervoltage lockout to enhance reliability and safety.
Its small size and high efficiency make it suitable for space-constrained applications like consumer electronics, industrial equipment, and communication devices. Additionally, the converter's ability to maintain high efficiency across a wide load range contributes to lower power consumption and extended battery life in portable applications.
Features
1. Input Voltage Range: It supports a wide input voltage range of 3.5 V to 28 V, making it versatile for various applications.
2. Output Current: The converter can deliver up to 2 A of continuous output current.
3. Efficiency: It boasts high efficiency across the load range, thanks to its integrated low-resistance MOSFETs.
4. Switching Frequency: It offers a fixed switching frequency of 700 kHz, optimizing efficiency and size.
5. Mode: Includes an Eco-mode for light-load efficiency, reducing operating current to minimize power loss.
6. Soft Start: Programmable soft-start feature allows for control over inrush current upon powering up.
7. Protection Features: Equipped with overcurrent protection, thermal shutdown, and undervoltage lockout to ensure reliability and safety.
8. Package: Available in a small, thermally enhanced 8-pin SO PowerPAD™ package, aiding in heat dissipation.
These features make the TPS54239DDAR suitable for applications requiring efficient power conversion, such as in consumer electronics, industrial systems, or communications equipment.
