What are the key features of LM2633MTD?
- Triple-output current-mode PWM controller enables multi-rail power sequencing from a single IC, reducing component count
- Wide auxiliary input range of 5 to 30V alongside a 4.5–5.5V primary input provides flexible power architecture support
- Current-mode control with pulse width modulation delivers fast transient response and precise output regulation for sensitive digital loads
What is LM2633MTD used for?
The LM2633MTD is designed for desktop PC motherboards, server power modules, and embedded computing platforms that require multiple regulated voltage rails from a single controller. Its triple-output architecture allows simultaneous regulation of core CPU voltage, I/O voltage, and chipset supply rails, simplifying system power design. The current-mode PWM control technique ensures stable operation and fast load transient response in high-current multi-output applications.

Frequently Asked Questions
How many output channels does the LM2633MTD control?
The LM2633MTD is a triple regulator controller that can manage three separate output voltage rails simultaneously. This makes it well-suited for PC motherboards and embedded platforms that require multiple power rails such as CPU core, memory, and I/O voltages from a single controller IC.
What input voltage range does the LM2633MTD support?
The LM2633MTD has a primary input voltage range of 4.5V to 5.5V (nominal 5V). It also requires an additional auxiliary input voltage in the range of 5 to 30V to support higher-voltage switching stages, providing flexibility in multi-rail power system design.
What control technique does the LM2633MTD use?
The LM2633MTD uses current-mode pulse width modulation (PWM) control. Current-mode control provides inherent cycle-by-cycle current limiting, improved line transient response, and simplified compensation network design compared to voltage-mode PWM controllers, making it ideal for demanding PC power applications.
What package does the LM2633MTD come in and is it RoHS compliant?
The LM2633MTD comes in a Small Outline (TSSOP or similar SO) package as indicated by the MTD suffix. Note that the Pbfree Code is listed as No, meaning this part may contain lead (Pb) and may not be fully RoHS compliant — verify specific compliance requirements with the distributor or datasheet before use in restricted markets.
