Frequently Asked Questions
What is the output voltage and current rating of the LM3676SD-1.8?
The LM3676SD-1.8 provides a fixed 1.8V output voltage with a maximum continuous output current of 600mA, making it suitable for powering low-voltage digital logic, microcontrollers, and memory devices.
What input voltage range does the LM3676SD-1.8 support?
The device accepts an input voltage from 2.9V to 5.5V, with a nominal operating point of 3.6V. This range covers single-cell Li-ion batteries (3.0V–4.2V) as well as regulated 5V USB or adapter supplies.
What control method does the LM3676SD-1.8 use, and why does it matter?
It uses voltage-mode pulse width modulation (PWM) control, which provides low output ripple and predictable transient response. This makes it ideal for noise-sensitive analog and RF circuits that share the 1.8V rail.
What package does the LM3676SD-1.8 come in, and are there alternative footprints?
The LM3676SD-1.8 is housed in an 8-pin SOT-23 (WSON) package (JESD-30 code R-XDSO-N8), which has a very small PCB footprint. Texas Instruments offers similar converters in other packages if a different footprint is required.
Is the LM3676SD-1.8 RoHS compliant?
According to available data, the LM3676SD-1.8 carries a Pbfree code of 'No', indicating the specific date code may use lead-based solder. Buyers should verify the exact production lot code and consult Texas Instruments' compliance documentation to confirm RoHS status for their region.
