- Wide input voltage range of 2V to 5.5V covers single-cell alkaline, NiMH, and Li-ion battery chemistries
- Single-function regulated charge pump in an 8-pin MSOP delivers clean boosted rails for noise-sensitive analog circuits
- MSL e3 rated and tape-and-reel packaged for automated high-volume PCB assembly
Applications
The LTC1751EMS8#TRPBF is used in battery-powered handheld instruments and portable audio devices that need a boosted voltage rail without the noise or size penalty of an inductor-based converter. Its 2V to 5.5V input range accommodates single-cell Li-ion and multi-cell alkaline battery stacks, making it versatile for IoT sensor nodes and wearables. Noise-sensitive analog front ends such as LCD bias generators and operational amplifier supply doublers benefit from its inductor-free switching topology.

Frequently Asked Questions
Why choose the LTC1751EMS8#TRPBF over an inductor-based boost converter for a compact 3.3V to 5V step-up rail?
The LTC1751EMS8#TRPBF uses a switched-capacitor charge pump that needs only small ceramic capacitors rather than an inductor, reducing EMI and shrinking the solution footprint to fit within an 8-pin MSOP footprint — critical when board area is less than 10mm x 10mm and radiated noise must be minimized near analog sensors.
What input voltage range does the LTC1751EMS8#TRPBF support, and which battery chemistries does it cover?
The LTC1751EMS8#TRPBF accepts inputs from 2V to 5.5V, which spans single-cell Li-ion at 2.7V to 4.2V, two-cell NiMH at 2.0V to 3.0V, and regulated 3.3V or 5V USB-derived rails, making it compatible with most portable battery-powered system architectures without additional voltage translation.
How does the 8-pin MSOP package of the LTC1751EMS8#TRPBF compare to DIP-8 in terms of PCB area for space-constrained designs?
The 8-pin MSOP package of the LTC1751EMS8#TRPBF occupies approximately 3mm x 3mm, which is over 70% smaller than a DIP-8 footprint at roughly 10mm x 7mm, allowing designers to allocate the saved PCB area to additional circuitry or battery capacity in wearable and IoT products.
Is the LTC1751EMS8#TRPBF suitable for LCD bias or op-amp supply doubling in a noise-sensitive audio front end?
Yes, the LTC1751EMS8#TRPBF is well suited for LCD bias generation and op-amp supply doubling in audio front ends because its inductor-free switched-capacitor topology generates significantly less broadband switching noise than inductive converters, and its 2V to 5.5V input range covers the typical single-supply audio rails of 2.7V to 5V.
