FAN5026MTC

Special Purpose Regulators Overview

The FAN5026MTC is a dual-output PWM controller designed for DDR power applications. It operates with an input voltage range of 3V to 16V and provides two adjustable output voltages from 0.9V to 5.5V. The device integrates high-side and low-side drivers for efficient switching regulation. It utilizes a 28-pin TSSOP package, suitable for compact board layouts in memory subsystems requiring precise voltage control.

Special Purpose Regulators Feature Summary

• Dual independent output channels for simultaneous DDR core and I/O power supply generation
• Integrated high-side and low-side gate drivers for simplified external component count
• Adjustable output voltage range supporting standard DDR logic levels

Special Purpose Regulators Applications

• DDR memory module power supplies
• Dual-output DC-DC conversion systems
• Portable computing devices requiring multiple voltage rails

Special Purpose Regulators Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or onsemi, noting corporate acquisition history. Confirm the 28-TSSOP package marking matches official datasheet silkscreen specifications. Ensure the part number suffix aligns with the specific tape-and-reel or tube packaging variant required for your assembly process. Cross-reference the date code against current production status to avoid obsolete stock.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for DDR memory interfaces requiring two distinct regulated outputs. It is appropriate for systems needing a wide input voltage tolerance between 3V and 16V. Consider its integration level if minimizing external driver components is a priority. Evaluate thermal performance within the TSSOP package relative to your expected load currents and ambient conditions.

Special Purpose Regulators Part Context

This controller belongs to the FAN5026 family of dual-output PWM controllers originally developed by Fairchild Semiconductor. Following onsemi's acquisition of Fairchild's semiconductor business, these parts are now managed under the onsemi portfolio. The series targets high-efficiency power management solutions for complex digital logic loads.

Special Purpose Regulators Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the 3V-16V input range and 0.9V-5.5V output adjustability. Ensure the replacement supports the same 28-TSSOP footprint and meets identical electrical characteristics for DDR applications.
