Frequently Asked Questions
What input voltage range does the LM25088MHX-1/NOPB support?
The LM25088MHX-1/NOPB accepts an input voltage from 4.5V to 42V, with a nominal design point of 24V. This wide input range makes it highly versatile for use in industrial 24V bus systems, automotive 12V rails, and telecom equipment where the input supply may vary significantly over operating conditions.
What control method does the LM25088MHX-1/NOPB use?
The LM25088MHX-1/NOPB uses current-mode pulse-width modulation (PWM) control. Current-mode control provides inherent cycle-by-cycle current limiting, improved line transient response, and simplified loop compensation compared to voltage-mode designs, making it a preferred topology for robust industrial power supply applications.
Is the LM25088MHX-1/NOPB synchronous or non-synchronous?
The LM25088MHX-1/NOPB is a non-synchronous buck controller, meaning it requires a single external power MOSFET and a rectifier diode rather than two power switches. This simplifies the external design and reduces cost in applications where efficiency is secondary to simplicity and cost-effectiveness.
Is the LM25088MHX-1/NOPB RoHS compliant?
Yes, the LM25088MHX-1/NOPB is lead-free and RoHS compliant, as indicated by its Pb-free code and JESD-609 'e3' classification. The '/NOPB' suffix in the part number explicitly denotes that the device is manufactured without lead, meeting global environmental standards for electronics.
