The MAX8958EWW+T from Maxim Integrated is a high-performance, dual-phase, synchronous step-down regulator specifically designed for powering portable devices that require high current, excellent load transient response, and high efficiency. This advanced power solution is ideal for applications in smartphones, tablets, and other handheld devices.

Key Features

• Input Voltage Range: The device supports a wide input voltage range from 2.5V to 5.5V, making it suitable for use in systems powered by single-cell lithium-ion (Li+) batteries or from 5V supply rails.
• Dual-Phase Operation: The MAX8958EWW+T operates in dual-phase mode, which helps in reducing input and output ripple, improving transient response, and allowing for the use of smaller, less expensive output capacitors.
• High Efficiency: Designed with efficiency in mind, it achieves up to 95% efficiency, which is critical for maximizing battery life in portable applications.
• Programmable Switching Frequency: The switching frequency is programmable from 500kHz to 2MHz, which allows designers to optimize the regulator for efficiency or component size.
• Integrated MOSFETs: The internal high-side and low-side MOSFETs provide a compact solution and reduce external component count.
• Thermal Management: The device features excellent thermal performance due to its thermally enhanced WLP (wafer-level package).

Performance and Protection

MAX8958EWW+T incorporates a number of features to ensure reliable operation under various conditions. It includes cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection. Furthermore, the regulator offers a Power-OK (POK) output to indicate when the output is in regulation.

Design Flexibility

With its compact size and comprehensive feature set, the MAX8958EWW+T offers designers significant flexibility. The device is available in a space-saving, 30-bump wafer-level package (WLP) with a 2.5mm x 3.0mm footprint. Its small size and high level of integration make it an excellent choice for space-constrained applications.

Conclusion

The MAX8958EWW+T from Maxim Integrated is an advanced, highly integrated power management solution that delivers high efficiency, excellent transient response, and a high degree of flexibility for designers working on the latest portable electronic devices.
