Frequently Asked Questions
What is the input voltage range of the LM3671MF-1.2?
The LM3671MF-1.2 accepts an input voltage from 2.7V to 5.5V, with a nominal operating point of 3.6V. This range makes it compatible with single-cell Li-ion batteries as well as regulated 5V rails.
What output current can the LM3671MF-1.2 supply?
The LM3671MF-1.2 can deliver up to 600mA continuous output current at 1.2V, making it suitable for powering DSP cores, FPGAs, and microcontrollers that require a stable 1.2V supply.
What control modes does the LM3671MF-1.2 support?
The LM3671MF-1.2 supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) control techniques. PWM mode is used under moderate to heavy loads for low output ripple, while PFM mode reduces switching losses at light loads to extend battery run time.
What package does the LM3671MF-1.2 come in?
The LM3671MF-1.2 is available in a 5-pin SOT-23 (R-PDSO-G5) surface-mount package, which measures approximately 2.9mm x 1.6mm. This tiny footprint is ideal for compact, space-constrained PCB designs.
