LT1610CMS8#PBF

Overview

The LT1610CMS8#PBF is a monolithic step-up DC/DC converter manufactured by Analog Devices Inc. It operates from a single lithium-ion cell or battery source to generate regulated output voltages. The device integrates a 1.7MHz switching frequency, allowing for the use of small external inductors and capacitors. It features an internal power switch capable of delivering up to 500mA of continuous current. The converter supports input voltage ranges typical for single-cell applications and includes protection features such as thermal shutdown and current limiting.

Feature Summary

• Integrates a high-efficiency power switch and control circuitry for compact design
• Operates at a fixed 1.7MHz switching frequency to minimize passive component size
• Includes built-in thermal shutdown and cycle-by-cycle current limiting for reliability

Applications

• Portable instrumentation powered by single-cell batteries
• Battery-operated medical devices requiring efficient voltage regulation
• Industrial sensor nodes utilizing single-cell power sources

Procurement Notes

Verify the specific suffix CMS8 against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with required input voltage levels for single-cell lithium applications. Cross-reference datasheet revision dates to confirm pinout and electrical characteristics match your design requirements before finalizing procurement.

Selection Notes

Select this component when designing systems powered by a single lithium-ion cell requiring a higher regulated output voltage. Consider the 1.7MHz frequency trade-off between component size and efficiency. Verify that the load current does not exceed the internal switch limits and that thermal management aligns with the device's shutdown specifications under expected ambient conditions.

Part Context

This part belongs to the LT1610 family of step-up converters designed for low-power, space-constrained applications. It is distinct from other ADI regulators by its specific integration of a 500mA switch and 1.7MHz operation. The MSOP-8 package variant offers a compact footprint suitable for dense PCB layouts in portable electronics.
