MAX8668ETEP+

Overview

The MAX8668ETEP+ is a quad-output power management IC featuring two synchronous buck converters and two low-dropout regulators. The buck outputs provide adjustable voltages from 0.6V to 3.3V with current ratings of 600mA and 1.2A respectively, while the LDOs deliver a fixed 3.3V at 300mA. Operating at a 1.5MHz switching frequency, the device accepts an input voltage range of 2.6V to 5.5V. It is housed in a 16-TQFN (3x3) package and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual synchronous step-down DC-DC converters and dual linear regulators for comprehensive power distribution.
• Features individual enable controls for independent output management and power optimization.
• Utilizes a high-frequency 1.5MHz switching architecture to minimize external component size.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-operated systems needing efficient power conversion
• Embedded applications with space-constrained PCB layouts

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to supply restrictions or end-of-life status. Confirm that the specific suffix matches the required pinout and thermal characteristics for your design. Review the latest datasheet for any updates regarding compliance standards or recommended operating conditions before finalizing procurement plans.

Selection Notes

Select this component when a single solution is needed to generate four distinct voltage levels from a single input source. Ensure the load requirements align with the specific current capabilities of each channel, particularly noting the difference between the 1.2A and 600A buck outputs. Verify that the system input voltage remains within the specified 2.6V to 5.5V window for proper regulation.

Part Context

This device belongs to the MAX8668 family of integrated power management solutions designed for portable electronics. It consolidates multiple regulator functions into a compact footprint, reducing board space compared to discrete solutions. The series is characterized by high efficiency and flexible configuration options for various power rail requirements.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify compatibility of electrical parameters such as output current and switching frequency if substituting with other models.
