What are the key features of LTC1751EMS8#PBF?
- Inductorless switched-capacitor charge pump architecture generating a boosted output using only small external capacitors, eliminating inductor EMI and cost
- Wide input voltage range from 2V to 5.5V supporting single-cell Li-ion, 2x AA alkaline, and 3.3V/5V regulated supply inputs
- Single-function 8-pin MSOP-8 package enabling simple integration into space-constrained portable and battery-powered product designs
What is LTC1751EMS8#PBF used for?
The LTC1751EMS8#PBF is designed for portable battery-powered applications that need to boost a depleted single-cell lithium or alkaline supply to a higher regulated voltage without an inductor. It is commonly used in handheld consumer devices, wireless sensor nodes, and LCD bias supplies where the 2V to 5.5V input range covers the full battery discharge curve. The switched-capacitor topology eliminates magnetic EMI, simplifying FCC/CE compliance for compact consumer electronics.

Frequently Asked Questions
Does LTC1751EMS8#PBF require an inductor, and what external components are needed?
No, the LTC1751EMS8#PBF uses a switched-capacitor (charge pump) topology and requires only small external flying capacitors and output filter capacitors—typically 1 µF to 10 µF ceramic capacitors. This eliminates the inductor, reducing BOM cost, board area, and EMI compared to traditional boost converter designs.
What is the input voltage range of LTC1751EMS8#PBF and which battery chemistries does it support?
The device operates from 2V to 5.5V input with a nominal 2.7V. This range covers a fully discharged single-cell Li-ion at 2.7V, a pair of alkaline AA cells delivering 2.0V to 3.0V, as well as 3.3V and 5V regulated rails, making it versatile across multiple battery chemistries and supply architectures in portable designs.
For a handheld device running from a single AAA cell, how does LTC1751EMS8#PBF extend battery run time?
By boosting the AAA cell voltage from as low as 2V to the required system rail, the LTC1751EMS8#PBF allows the system to continue operating even as the cell discharges below the normal operating threshold of the load IC. This harvests energy that would otherwise be wasted, extending run time by up to 20-30% compared to designs with a fixed low-voltage cutoff at 2.7V or above.
When is LTC1751EMS8#PBF preferred over an inductor-based boost converter for a 5V LCD bias supply?
LTC1751EMS8#PBF is preferred when the output current requirement is low (typically below 100 mA), when radiated EMI must be minimized to pass FCC Class B limits without a shield, and when PCB height is constrained to exclude tall inductors. The MSOP-8 package with external 1 µF capacitors occupies under 20 mm2 of board space, significantly less than most inductor-based boost solutions.
