Frequently Asked Questions
What is the output voltage of the LM2681M6/NOPB?
The LM2681M6/NOPB generates an unregulated output equal to approximately 2× the input voltage (2×VIN). For example, with a 3.3V input the output is roughly 6.6V (minus diode drops and load regulation losses). The actual output will vary with load current and input voltage.
What external components does the LM2681 require?
The LM2681 requires only two external capacitors — a charge pump capacitor (typically 1µF to 10µF) and an output filter capacitor (typically 10µF to 100µF). No inductors are needed, making it ideal for compact, low-noise designs.
What is the maximum output current of the LM2681M6/NOPB?
The LM2681M6/NOPB can supply up to 100mA of continuous output current. Output current capability depends on the input voltage, the value of the charge pump capacitor, and the oscillator frequency (70kHz typical, up to 150kHz).
Is the LM2681M6/NOPB RoHS compliant and lead-free?
Yes. The /NOPB suffix designates a lead-free, RoHS-compliant version. It uses a Pb-free tin finish on the SOT-23-6 package, meeting EU RoHS Directive 2011/65/EU and REACH requirements.
What are common alternatives to the LM2681M6/NOPB?
Compatible alternatives include the Texas Instruments LM2686M6/NOPB (regulated doubler variant), Maxim MAX660ESA+ (switched-capacitor voltage converter, SOIC-8), and the Microchip TC1044SEOA (CMOS voltage converter, ±20mA). Each has slightly different input ranges and output current ratings, so check the datasheet before substituting.
