What are the key features of LTC1261LCMS8-4.5#PBF?

Fixed -4.5V output from a 5V input using switched-capacitor topology, eliminating inductors for a simpler BOM
Tight input voltage range of 4.75V to 5.25V ensures stable negative-rail generation in 5V-only systems
Compact MSOP-8 (MS8) package with lead-free (PBF) RoHS-compliant construction for modern PCB designs
Voltage-mode control with low quiescent current, suitable for noise-sensitive analog and mixed-signal applications

What is LTC1261LCMS8-4.5#PBF used for?

The LTC1261LCMS8-4.5#PBF is well suited for generating a negative supply rail in portable instruments, data acquisition systems, and op-amp bias circuits powered from a single 5V source. Its switched-capacitor design makes it ideal for LCD bias supplies, RS-232 transceivers, and analog front-end circuits where an inverting charge-pump is needed without a bulky inductor. The RoHS-compliant PBF package makes it appropriate for consumer electronics and industrial sensor modules requiring compact, clean negative-voltage generation.

Frequently Asked Questions

What output voltage does the LTC1261LCMS8-4.5#PBF produce and from what input range?

The LTC1261LCMS8-4.5#PBF generates a fixed -4.5V output from an input voltage range of 4.75V to 5.25V (nominal 5V). This makes it a convenient single-supply solution for creating a negative rail without any inductors, using a switched-capacitor charge-pump architecture.

Which applications benefit most from the LTC1261LCMS8-4.5#PBF switched-capacitor inverter?

Typical applications include RS-232 transceiver bias, LCD panel negative-supply rails, op-amp dual-supply circuits, and data acquisition front-ends needing a clean -4.5V rail. The inductor-free switched-capacitor topology keeps board space below 50 mm² for the power section, making it ideal for compact handheld instruments.

How does the MSOP-8 package size of LTC1261LCMS8-4.5#PBF compare to standard SOIC-8 for board-space-critical layouts?

The MSOP-8 (MS8) package occupies roughly 9 mm² of PCB area, compared to approximately 29 mm² for a standard SOIC-8, saving about 20 mm² per device. This size advantage, combined with the charge-pump's inductor-free design, makes the LTC1261LCMS8-4.5#PBF a strong choice for high-density mixed-signal boards.

Is LTC1261LCMS8-4.5#PBF RoHS compliant and what does the PBF suffix indicate?

Yes, the PBF (Pb-Free) suffix confirms the LTC1261LCMS8-4.5#PBF is manufactured with lead-free solder terminations, meeting RoHS and REACH compliance standards. The part uses a tin-based finish on the 8-pin MSOP package, suitable for wave or reflow soldering at standard lead-free profiles up to 260°C peak.
