MAX799CSE+

Overview

The MAX799CSE+ is a synchronous step-down DC-DC controller designed for CPU voltage regulation. It operates with an input voltage range of 3V to 6V and delivers up to 10A output current. The device features a fixed switching frequency of 300kHz and supports output voltages from 2.5V to 6V, including standard 3V and 5V rails. It utilizes a buck topology with a maximum duty cycle of 96%. The component functions within a commercial temperature range of 0°C to +70°C and is housed in a surface-mount SOIC-Narrow-16 package.

Feature Summary

• Synchronous buck controller architecture optimized for high-efficiency power conversion
• Integrated error amplifier and compensation network for stable loop response
• Fixed 300kHz switching frequency reduces external component size
• Designed specifically for low-voltage, high-current processor core supplies

Applications

• CPU core voltage regulation
• Point-of-load DC-DC conversion
• Low-voltage power rail generation

Procurement Notes

Verify the exact suffix designation against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status through the specific product release documentation. Ensure the ordering part number matches the required package variant. Cross-reference the revision level with the latest public technical specifications to avoid integration errors.

Selection Notes

Select this component when designing systems requiring a compact, synchronous solution for low-voltage processor cores. It is suitable for applications where a fixed 300kHz frequency is acceptable and input voltages remain between 3V and 6V. Consider the thermal performance of the SOIC-16 package for the intended load current and ambient conditions.

Part Context

This device belongs to the Maxim Integrated family of specialized power management ICs. It is engineered to meet the stringent transient and efficiency requirements of modern digital logic families.
