Frequently Asked Questions
What is the output current rating of the LM20134MH/NOPB?
The LM20134MH/NOPB is rated for up to 4A continuous output current, making it suitable for powering DSP cores, FPGAs, microprocessors, and memory arrays that require moderate current at regulated low voltages such as 1.0V, 1.2V, or 1.8V stepped down from a 5V system bus.
What input voltage range does the LM20134MH/NOPB support?
The LM20134MH/NOPB accepts input voltages from 2.95V to 5.5V, with a nominal operating voltage of 5V. This range is optimized for use with 3.3V and 5V power bus systems common in embedded computing, communications, and industrial control applications.
Does the LM20134MH/NOPB support input clock synchronization?
Yes, the LM20134MH/NOPB includes an external clock synchronization input (SYNC) that allows the switching frequency to be locked to an external reference clock. This feature reduces switching noise interference in RF and high-resolution analog designs by synchronizing the regulator's switching events with the system clock to simplify EMI filtering.
Is the LM20134MH/NOPB available in an automotive-grade version?
Yes, the LM20134MH/NOPB can be obtained in an automotive-grade variant meeting AEC-Q100 qualification requirements for use in vehicle electronics. Automotive-grade devices undergo additional stress testing and reliability screening, making them appropriate for in-vehicle infotainment, ADAS sensor modules, and instrument cluster power supplies operating over the automotive temperature range of -40°C to 125°C.
