Maxim Integrated MAX8839EWE+T Power Management IC

The Maxim Integrated MAX8839EWE+T is a highly integrated power management integrated circuit (PMIC) designed to provide a comprehensive power solution for portable devices. This advanced IC combines a step-down converter with dual linear regulators, making it an ideal choice for space-constrained applications such as smartphones, tablets, and other handheld devices.

Efficient Power Conversion

The MAX8839EWE+T features a high-efficiency, synchronous, step-down DC-DC converter that is capable of delivering up to 2A of continuous output current. This converter operates over a wide input voltage range and provides a fixed or adjustable output voltage, allowing for flexible design options to meet specific application requirements.

Dual Linear Regulators

Accompanying the step-down converter are two low-dropout linear regulators (LDOs) that offer additional power rails for peripheral components. These LDOs are designed to supply clean and stable voltage with high accuracy, which is crucial for sensitive RF and analog circuits. The output voltage of each LDO can be programmed via external resistors, providing further versatility to the design engineer.

Compact and Robust Design

The MAX8839EWE+T comes in a compact, 16-pin WLP (Wafer-Level Package) that occupies minimal board space, making it a perfect fit for portable electronics where space is at a premium. Despite its small size, it is built to withstand the rigors of mobile environments, featuring built-in thermal overload protection, short-circuit protection, and under-voltage lockout to ensure reliable operation under various conditions.

Simple Integration

With an integrated power-on reset and power-good output, the MAX8839EWE+T simplifies system power sequencing and monitoring. It also supports a variety of switching frequencies, enabling designers to optimize performance for their specific application, whether the priority is maximizing efficiency or minimizing external component size.
