What are the key features of LTC1751EMS8?
- Charge pump topology generates a regulated voltage-doubled output from a 2 V to 5.5 V input with no inductors required
- Compact 8-pin MSOP package minimizes board area in portable and space-constrained power-supply designs
- Wide 2 V to 5.5 V input range supports single-cell Li-Ion, two-cell alkaline, and regulated 3.3 V or 5 V supply rails
What is LTC1751EMS8 used for?
The LTC1751EMS8 is used in portable battery-powered devices that require a higher supply voltage for SRAM data retention, LCD contrast generation, or EL backlight drives from a single low-voltage cell. Its inductor-free charge pump design minimizes EMI and simplifies layout compared to boost converters, making it a preferred solution for handheld instruments, wearables, and low-power embedded systems.

Frequently Asked Questions
What input voltage range does the LTC1751EMS8 support, and what output voltage can it generate?
The LTC1751EMS8 accepts an input voltage between 2 V and 5.5 V and operates with a nominal input of 2.7 V, producing a doubled output voltage through its switched-capacitor architecture. For example, from a 3.3 V supply the charge pump generates approximately 6.6 V, suitable for driving LCD contrast circuits or biasing analog components that require higher supply voltages.
Why choose an inductor-free charge pump like the LTC1751EMS8 instead of a boost converter for low-power applications?
Charge pump converters like the LTC1751EMS8 eliminate the inductor entirely, reducing board area by removing a component that typically occupies 4 mm × 4 mm or more. This also reduces EMI because there is no switching magnetic field, which is critical in RF and audio applications where inductor-generated interference would degrade SNR.
Which portable and embedded applications commonly use the LTC1751EMS8?
This charge pump is commonly used to supply SRAM data-retention voltages in portable meters, generate LCD contrast bias in embedded displays, and power EL backlight inverters in handheld instruments operating from a single 2-cell AA or 3.3 V regulated rail. Its tiny 8-pin MSOP footprint fits into tightly packed PCB layouts with less than 50 mm² allocated to the power subsystem.
How does the LTC1751EMS8 compare to through-hole or larger-package charge pumps in terms of PCB integration?
The 8-pin MSOP package of the LTC1751EMS8 measures approximately 3 mm × 3 mm, which is significantly smaller than SO-8 or DIP-8 alternatives, saving up to 60 % of PCB footprint for the same charge pump function. Combined with only 2 external flying capacitors typically in the 1 µF to 10 µF range, the total solution area remains well under 50 mm², ideal for miniaturized portable products.
