What are the key features of LT1614CMS8#PBF?
- Inverting PWM topology generates negative rails down to -24 V from input voltages as low as 0.92 V, enabling single-supply negative bias generation
- Current-mode control with internal compensation reduces external component count to as few as 4 passives in the 8-pin MSOP footprint
- Input range of 0.92 V to 6 V covers single-cell Li-ion and regulated 3.3 V/5 V rails, providing design flexibility across battery and bus-powered systems
What is LT1614CMS8#PBF used for?
The LT1614CMS8#PBF is used to generate negative bias rails for op-amp dual supplies, LCD contrast voltage, and CCD bias circuits in portable instruments. Its low minimum input of 0.92 V makes it suitable for single-cell boost-then-invert architectures in handheld medical devices and industrial sensor conditioning boards.

Frequently Asked Questions
What input voltage range does LT1614CMS8#PBF accept and what negative output voltage can it reach?
The LT1614CMS8 accepts input voltages from 0.92 V to 6 V and can generate output voltages as negative as -24 V. This wide input range covers single-cell alkaline, NiMH, and Li-ion batteries as well as regulated 3.3 V and 5 V system rails.
How does the current-mode PWM control of LT1614CMS8#PBF improve loop stability in inverting converter designs?
Current-mode control in the LT1614CMS8 provides inherent cycle-by-cycle current limiting and simplifies compensation because the inductor appears as a first-order element to the voltage feedback loop. Designers can stabilize the converter with a single 100 nF to 470 nF output capacitor and one resistor-capacitor network, reducing design time compared to voltage-mode alternatives.
Which PCB footprint does LT1614CMS8#PBF use and how does it compare to alternative SO-8 packages for board space?
The device uses an 8-pin MSOP package measuring 3 mm x 3 mm, roughly 40 % smaller in board area than a standard SO-8 package at 4.9 mm x 3.9 mm. This size advantage is significant in portable instruments and handheld devices where negative bias rail generation must fit in under 10 mm² of PCB area.
