FAN5233MTC

Special Purpose Regulators Overview

The FAN5233MTC is a high-efficiency DC/DC controller designed for notebook and portable applications. It features an input voltage range of 5.4V to 24V and provides five regulated outputs: two PWM outputs at 5V @ 5A and 3.3V @ 5A, one always-on 5V linear output at 50mA, plus 12V and adjustable outputs. The device operates between -20°C and +85°C in a surface-mount package.

Special Purpose Regulators Feature Summary

• Integrates multiple regulated outputs including PWM and linear regulators for system power management
• Supports wide input voltage range suitable for battery-powered portable devices
• Includes an always-on linear regulator output for standby power requirements

Special Purpose Regulators Applications

• Notebook computers
• Mobile PCs
• Portable electronic devices

Special Purpose Regulators Procurement Notes

Verify the exact revision level and date code upon receipt, as this component is listed as obsolete by the manufacturer. Ensure compatibility with existing PCB footprints and thermal management designs. Confirm that alternative sources provide genuine parts with valid traceability documentation to avoid counterfeit risks associated with end-of-life components.

Special Purpose Regulators Selection Notes

Select this controller when designing systems requiring multiple distinct voltage rails from a single input source. It is appropriate for space-constrained portable applications where integrated power management reduces component count. Consider thermal dissipation requirements for the 5A PWM outputs during selection.

Special Purpose Regulators Part Context

This part belongs to Fairchild's special purpose regulator family, specifically optimized for mobile computing platforms. It consolidates power conversion functions typically handled by discrete controllers, simplifying the bill of materials for laptop and tablet power architectures.

Special Purpose Regulators Replacement Considerations

The FAN5233MTCX is a compatible variant within the same product line. Verify pinout and electrical specifications against current design requirements before substitution.
