36V, 0.6A, 2MHz Step-Down Converter in TSOT23-6 Package (NRND Status)
The MP2451DT-LF-Z is a high-frequency (2MHz) step-down switching regulator with an integrated high-side power MOSFET. Operating over a wide input voltage range of 3.3V to 36V, it delivers up to 0.6A of output current with fast transient response. Its ultra-low shutdown current (3µA) and high 2MHz switching frequency allow for extremely small inductor/capacitor footprints, making it popular for automotive, industrial, and meter-reading control boards. Although marked as Not Recommended for New Designs (NRND) by MPS, it maintains a huge installed base with strong spot-market demand for repairs and maintenance.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Why is the 2MHz high switching frequency advantageous for this power chip?
The high 2MHz switching frequency allows engineers to use significantly smaller inductors and ceramic capacitors, optimizing overall PCB board space and reducing BOM component sizes.
What makes this chip still popular in spot market procurement despite its NRND status?
Due to its widespread adoption in legacy industrial control, automotive sub-modules, and smart grid meters, many clients prefer sourcing spot stock to avoid expensive PCB re-layouts and secondary re-certification processes.
