LTC3410BESC6#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3410BESC6#TRPBF is a micropower synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 5.5V and provides a fixed 1.8V output at up to 300mA. The device utilizes a constant frequency, current-mode architecture with a switching frequency of 2.25MHz. Key electrical specifications include a quiescent current of 10nA in shutdown mode and a typical operating supply current of 300µA. It is housed in a compact SC-70-6 package and supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-efficiency synchronous rectification within a monolithic buck regulator topology for improved power conversion performance.
• Features a constant frequency, current-mode control architecture that ensures stable operation across varying load conditions.
• Provides ultra-low shutdown quiescent current to maximize battery life in portable applications when the device is disabled.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable handheld devices requiring efficient power management from single-cell lithium-ion or alkaline batteries
• Embedded systems utilizing microcontrollers or DSPs that require regulated low-voltage power supplies
• Battery-operated consumer electronics where space constraints necessitate small surface-mount packaging

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration distinct from cut-tape variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the fixed 1.8V output variant matches the system design requirements, as other fixed voltage options exist within the same family. Cross-reference the SC-70-6 footprint dimensions against PCB layout guidelines provided in the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V output is required rather than an adjustable version. The 300mA output current capability suits low-power digital loads but may be insufficient for higher current applications requiring the LTC3414 series. The 2.25MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the input voltage source remains within the 2.5V to 5.5V operational window to ensure proper regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3410 family of micropower synchronous buck converters designed for space-constrained portable electronics. It shares architectural similarities with other members like the LTC3410ESC6 but differs in output voltage configuration and packaging type. The ESC6 designation typically refers to the commercial grade temperature range and SC-70-6 package, distinguishing it from wider temperature or larger package variants.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LTC3410ESC6-1.8#TRMPBF offers identical electrical characteristics but comes in cut-tape packaging instead of reel. For adjustable output requirements, consider the LTC3410ESC6 without the voltage suffix. Higher current needs may require upgrading to the LTC3414EFE#TRPBF series.
