- 2.25 MHz switching frequency enabling use of tiny 1 µH or smaller inductors
- Fixed 1.5 V output voltage with current-mode control for fast transient response
- Wide 2.5 V to 5.5 V input range compatible with Li-ion, Li-Po, and 3-cell NiMH battery stacks
- SOT-23-6 package occupying less than 10 mm² for space-critical wearable and IoT designs
Applications
The LTC3410ESC6-1.5#TRMPBF targets portable consumer electronics and wearable devices requiring a regulated 1.5 V rail from a single lithium-ion cell or USB-derived 5 V bus. Its 2.25 MHz switching frequency keeps the external inductor and capacitors extremely small, minimizing total solution size for Bluetooth sensor tags, hearing aids, and smartwatch subsystems. It also powers low-voltage microcontrollers and memory ICs in handheld instruments where a compact, efficient 300 mA supply is needed alongside a primary battery without bulky magnetic components.

Frequently Asked Questions
What output current and switching frequency does the LTC3410ESC6-1.5#TRMPBF support, and how do these parameters constrain inductor selection?
The LTC3410ESC6-1.5#TRMPBF delivers up to 300 mA continuous output current and switches at 2.25 MHz. At this high switching frequency, inductors as small as 1 µH with a saturation current rating above 350 mA are sufficient, allowing component heights under 1 mm and a total solution footprint under 10 mm², which is ideal for wearable and handheld device PCBs.
Over what input voltage range does the LTC3410ESC6-1.5#TRMPBF regulate its 1.5 V output, and which battery types does this cover?
The LTC3410ESC6-1.5#TRMPBF regulates correctly from input voltages between 2.5 V and 5.5 V, covering single-cell lithium-ion batteries discharging from 4.2 V down to 2.7 V, USB 5 V bus supplies, and 3-cell NiMH packs at nominal 3.6 V. The wide input range allows the same PCB design to run from multiple power sources without redesigning the regulator stage.
How does the SOT-23-6 package of the LTC3410ESC6-1.5#TRMPBF compare to a discrete MOSFET-based buck converter for a wearable heart-rate monitor?
The LTC3410ESC6-1.5#TRMPBF integrates both the high-side and low-side MOSFETs, a gate driver, and the control circuit into a SOT-23-6 footprint of roughly 1.6 mm × 2.9 mm. A discrete 300 mA buck converter with external MOSFETs and a dedicated controller would require at least 4 separate components and over 50 mm² of PCB area, making the integrated solution roughly 5 times smaller and far simpler to qualify for wearable medical accessories.
