FAN5019MTCX

Special Purpose Regulators Overview

The FAN5019MTCX is a 6-bit VID controller designed for 2-4 phase VRM10.X applications. It functions as a multi-phase DC-DC controller for high-current, low-voltage CPU core power regulation circuits. The component operates within an ambient temperature range of 0°C to 85°C and is housed in a 28-pin TSSOP package.

Special Purpose Regulators Feature Summary

• Supports 6-bit VID input for precise voltage control
• Configurable for 2 to 4 phase operation
• Compliant with VRM10.X specifications

Special Purpose Regulators Applications

• CPU core power regulation
• High-current low-voltage DC-DC conversion
• VRM10.X compliant system designs

Special Purpose Regulators Procurement Notes

Verify the specific revision level and pinout compatibility against the target motherboard schematic before integration. Confirm that the 28-pin TSSOP footprint matches the PCB layout requirements. Ensure the design supports the required phase count configuration. Check for any updated errata sheets from Fairchild Semiconductor regarding thermal performance under maximum load conditions.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring VRM10.X compliance with 2 to 4 phases. It is suitable for CPU core power stages needing 6-bit VID resolution. Consider thermal management solutions due to the high-current application context. Verify that the operating temperature range of 0°C to 85°C meets the environmental constraints of the final assembly.
