Frequently Asked Questions
What is the input voltage range of the LM2681M6?
The LM2681M6 operates over an input voltage range of 2.5V to 5.5V, with a nominal input of 5V. This makes it well-suited for single-cell Li-ion, 3.3V, and 5V system rails commonly found in portable and embedded applications.
What conversion modes does the LM2681M6 support?
The LM2681M6 is a switched capacitor converter that supports both voltage inversion (generating a negative output) and voltage doubling modes, allowing designers to derive a negative supply or a doubled positive rail from a single input voltage without using inductors.
What package does the LM2681M6 come in and what are the key dimensions?
The LM2681M6 is available in the SOT-23-6 (6-pin small-outline transistor) package, encoded as R-PDSO-G6 per JESD-30. This compact surface-mount package is ideal for space-constrained PCB designs in consumer electronics and portable instruments.
What are typical applications for the LM2681M6?
Typical applications include generating negative bias voltages for LCD panels, providing dual-supply rails for op-amps, powering RS-232 level shifters, and supplying negative references in handheld test equipment. Its charge-pump topology eliminates the need for an external inductor.
How can I purchase the LM2681M6 and what is the starting price?
The LM2681M6 is available from FindMyChip starting at approximately $0.43 per unit. You can submit a quote request directly on the product page for bulk pricing, lead time, and worldwide shipping options.
