Frequently Asked Questions
What is the input voltage range of the LM5574MT/NOPB?
The LM5574MT/NOPB accepts an input voltage from 6V to 75V, with a nominal operating point of 48V. This wide range makes it suitable for industrial 24V and telecom 48V bus applications.
What output voltage can the LM5574MT/NOPB regulate to?
The device supports an adjustable output voltage as low as 1.225V, set by an external resistor divider. The maximum output current is 0.5A, making it appropriate for low-power point-of-load regulation.
What control method does the LM5574MT/NOPB use?
It uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, improved line transient response, and simplified loop compensation compared to voltage-mode designs.
What package does the LM5574MT/NOPB come in?
The LM5574MT/NOPB is available in a 16-pin Small Outline Package (SOIC-16, R-PDSO-G16), suitable for surface-mount assembly. It is a lead-free (Pb-free) part compliant with RoHS requirements.
What are typical applications for the LM5574MT/NOPB?
Typical applications include industrial power supplies, telecom equipment running from 48V rails, factory automation controllers, building management systems, and embedded computing boards requiring a compact step-down regulator with a wide input range.
