Frequently Asked Questions
What is the input and output voltage range of the LM20133MH/NOPB?
The LM20133MH/NOPB accepts an input voltage from 2.95V to 5.5V (nominal 5V) and delivers up to 3A of continuous output current. The output voltage is adjustable depending on external resistor selection, making it flexible for a variety of point-of-load applications.
What control mode does the LM20133MH/NOPB use, and why does it matter?
The LM20133MH/NOPB uses current-mode pulse width modulation (PWM) control. This technique improves line regulation, simplifies loop compensation, and provides inherent cycle-by-cycle current limiting, which enhances both performance and protection in demanding power supply designs.
Is the LM20133MH/NOPB suitable for automotive applications?
Yes. The LM20133MH/NOPB is available in an optional automotive grade variant that meets AEC-Q100 qualification requirements. This makes it appropriate for use in automotive systems such as ADAS, infotainment units, and body control modules operating in wide temperature and harsh electrical environments.
What package does the LM20133MH/NOPB come in, and what is its pricing?
The LM20133MH/NOPB is housed in a 16-pin small outline (SOIC) package (JESD-30 code R-PDSO-G16), which is widely supported on standard PCB footprints. It is priced from approximately $2.34 and is available with worldwide shipping through global component distributors.
