Frequently Asked Questions
What is the LM2642MTC/NOPB used for?
The LM2642MTC/NOPB is a dual-phase synchronous step-down controller designed to power high-current loads such as multi-core CPUs, FPGAs, and ASICs in servers, workstations, and industrial computers. It manages two interleaved switching phases to reduce output current ripple and improve transient response.
What input and output voltage ranges does the LM2642MTC/NOPB support?
The LM2642MTC/NOPB accepts an input voltage from 4.5V to 30V, making it compatible with standard 5V and 12V power rails. The output voltage is programmable via a 2-bit VID interface from approximately 0.9V to 3.5V, enabling flexible processor core voltage selection.
What package does the LM2642MTC/NOPB come in and what is the pin count?
The LM2642MTC/NOPB is housed in a 28-pin TSSOP (Thin Shrink Small Outline Package) with an exposed thermal pad. The NOPB suffix confirms it is lead-free and RoHS compliant.
What are common alternatives to the LM2642MTC/NOPB?
Comparable dual-phase synchronous buck controllers include the ISL6545CB from Intersil and the NCP5381MNR2G from ON Semiconductor. Both support multi-phase operation and VID programming for CPU power supply applications. Verify pin-out and feature compatibility before substituting.
Is the LM2642MTC/NOPB RoHS compliant and what is its temperature range?
Yes, the NOPB suffix designates a lead-free, RoHS-compliant variant. The device is rated for an operating temperature range of -40C to 125C, suitable for industrial and harsh-environment applications.
