The MAX8839ERE+T from Maxim Integrated is a high-performance power-management integrated circuit (IC) designed to cater to the demanding requirements of portable electronic devices. This versatile component is an ideal solution for compact and energy-efficient power supply designs, providing a combination of features that enhance device performance and user experience.
Key Features
- Integrated Step-Down Converters: The MAX8839ERE+T includes two high-efficiency PWM step-down converters, which are capable of delivering a continuous output current of up to 2A each. This makes it suitable for powering core voltages of microprocessors and other power-hungry components.
- Multiple Linear Regulators: In addition to the step-down converters, the IC also integrates multiple linear regulators. These provide stable and noise-free supply voltages for sensitive analog circuits, RF modules, and other critical system components.
- Flexibility: With an input voltage range of 2.6V to 5.5V, the MAX8839ERE+T can operate from a single lithium-ion cell or other standard power sources, making it highly adaptable for various types of portable devices.
- Power-Saving Modes: It supports selectable power-saving modes, including a low-power pulse-skipping mode for light-load conditions, which helps to extend battery life in portable applications.
- Thermal Protection: The device includes thermal shutdown protection, which prevents damage from overheating by automatically reducing output current during high-temperature conditions.
Applications
The MAX8839ERE+T is suitable for a wide range of portable electronic applications, such as:
- Smartphones and Tablets
- Portable Media Players
- Handheld Gaming Devices
- Wireless Headsets and Earbuds
- GPS Devices
- Other battery-powered consumer electronics
Package and Availability
The MAX8839ERE+T is available in a compact, lead-free, 40-pin TQFN (6mm x 6mm) package, which is ideal for space-constrained applications. Its small footprint and high integration level reduce the need for additional external components, simplifying the design process and accelerating time-to-market for product developers.
