Frequently Asked Questions
What is the output voltage and current capability of the LM3671TLX-1.2/NOPB?
The LM3671TLX-1.2/NOPB provides a fixed 1.2V regulated output voltage with a maximum output current of 600 mA. The 1.2V output makes it suitable for powering digital logic cores, DRAM I/O, and low-voltage FPGA I/O banks directly from a single-cell Li-ion battery or a 5V USB supply, without requiring an intermediate linear regulator stage.
What switching frequency does the LM3671TLX-1.2/NOPB operate at?
The LM3671TLX-1.2/NOPB operates at a fixed 2 MHz PWM switching frequency, which is high enough to allow the use of very small inductors (typically 1–4.7 µH) and low-value output capacitors. This high frequency enables a very compact power supply solution, reducing the total converter footprint to only a few square millimeters when using miniature passive components.
Does the LM3671TLX-1.2/NOPB support light-load power saving?
Yes, the LM3671TLX-1.2/NOPB supports Pulse Frequency Modulation (PFM) mode at light loads in addition to standard PWM operation at heavy loads. In PFM mode, the converter skips switching pulses when the load is light, dramatically reducing switching losses and quiescent current. This dual-mode operation significantly extends battery life in portable IoT and wearable applications with intermittent load profiles.
What package is the LM3671TLX-1.2/NOPB available in?
The LM3671TLX-1.2/NOPB is available in a 5-ball DSBGA (Die-Sized Ball Grid Array) package, JESD-30 code R-PBGA-B5. This ultra-compact package, sometimes as small as 1 mm x 1 mm, is one of the smallest available for switching regulators and is specifically designed for space-constrained portable and wearable applications where traditional SOT-23 or TSOP packages are too large.
