- Inductor-free switched-capacitor charge pump topology
- 6-pin DFN package with less than 2mm × 2mm footprint
- Low quiescent current for efficient battery-powered operation
- No magnetic EMI from inductor switching for RF-sensitive designs
- Single supply rail simplifies power tree for 2-cell alkaline or single Li-Ion systems
Applications
LTC3240EDC-3.3#TRPBF is ideal for generating a regulated 3.3V supply from 2-cell alkaline, NiMH, or single-cell Li-Ion batteries in portable consumer electronics, wireless sensors, and wearable devices where inductor-free operation reduces EMI and board area. Its 1.8V to 5.5V input range seamlessly covers the full discharge curve of common battery chemistries without dropout. The tiny 6-pin DFN footprint makes it a popular choice for Bluetooth and Zigbee IoT nodes requiring a clean regulated rail from unregulated battery inputs.

Frequently Asked Questions
What input voltage range does LTC3240EDC-3.3#TRPBF support, and how does this cover single-cell Li-Ion battery operation?
LTC3240EDC-3.3#TRPBF accepts input voltages from 1.8V to 5.5V, which spans the full single-cell Li-Ion discharge range from 4.2V fully charged down to 2.7V near cutoff, and continues operating into the 1.8V range for 2-cell alkaline batteries at end-of-life. This eliminates premature power shutdown and maximizes battery runtime compared to regulators with a 2.5V or 3V minimum input.
Why does LTC3240EDC-3.3#TRPBF's charge pump topology reduce EMI compared to inductor-based buck-boost converters?
A switched-capacitor charge pump transfers energy through flying capacitors rather than an inductor, eliminating the magnetic field emissions that cause radiated EMI in inductor-based converters switching at 1 MHz or higher. This makes LTC3240EDC-3.3#TRPBF well-suited for RF-sensitive designs such as Bluetooth Low Energy modules, GPS receivers, and medical wireless sensors where inductor EMI can desensitize nearby antenna circuits.
How does LTC3240EDC-3.3#TRPBF compare in board footprint to a typical inductor-based buck-boost converter at the same 3.3V output?
LTC3240EDC-3.3#TRPBF occupies a 2mm × 2mm 6-pin DFN footprint and requires only 2–3 external flying capacitors totaling roughly 10–30 mm² of PCB area. A comparable inductor-based converter typically needs an additional 4mm × 4mm or larger inductor plus multiple input and output capacitors, consuming 2–3× more board space — a critical difference in wearables and hearing aids with limited PCB real estate.
