FAN2306MAMPX

Overview

The FAN2306MAMPX is a synchronous buck controller manufactured by Fairchild Semiconductor. It integrates high-side and low-side drivers for external N-channel MOSFETs, supporting input voltages from 4.5V to 28V with adjustable output voltages down to 0.6V. The device features a fixed 1MHz switching frequency and supports up to 6A output current. Key technical specifications include an operating junction temperature range of -40°C to +125°C and a supply voltage range of 4.5V to 28V.

Feature Summary

• Integrated high-side and low-side gate drivers designed for external N-channel power MOSFETs
• Fixed 1MHz switching frequency operation to optimize inductor size and transient response
• Built-in adaptive dead-time control to minimize cross-conduction losses during switching transitions
• Comprehensive protection mechanisms including over-current protection, thermal shutdown, and undervoltage lockout

Applications

• Point-of-load (POL) DC/DC converters for server and storage systems
• Industrial equipment power distribution networks
• Telecommunications infrastructure power supplies
• Consumer electronics requiring efficient step-down conversion

Procurement Notes

Verify the specific suffix 'MAMPX' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required for your region. Cross-reference the datasheet revision date to confirm pinout and electrical parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when designing synchronous buck converters requiring a fixed 1MHz frequency and support for input voltages up to 28V. It is suitable for applications needing integrated driver capabilities without external logic level shifters. Consider the PQFN package constraints for thermal management and PCB layout requirements compared to through-hole alternatives.

Part Context

This part belongs to the FAN230x family of synchronous buck controllers from Fairchild Semiconductor, now part of onsemi. These devices are engineered for high-efficiency power conversion in compact form factors. The MAMPX designation typically indicates a specific surface-mount package variant within this product line, optimized for automated assembly processes.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the FAN2306 or other members of the FAN230x series. Verify that any replacement maintains compatible input voltage ranges, switching frequencies, and pin configurations to ensure circuit functionality without redesign.
