LTC1504IS8#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC1504IS8#TRPBF is a monolithic step-down synchronous switching regulator manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 200 kHz and supports an input voltage range from 4 V to 10 V. The device delivers up to 800 mA of output current through a single adjustable or fixed output channel, with specific variants offering 3.3 V outputs. It features low quiescent current of 1 µA and operates within a temperature range of 0°C to +70°C. Packaged in an 8-lead SOIC surface-mount package, it includes shutdown functionality for power management.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status and manufacturing origin details prior to integration. Check for obsolescence notices or lifecycle changes directly from the manufacturer. Ensure thermal management solutions align with the SOIC-8 package limitations under expected operating conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck solution is required for inputs between 4 V and 10 V. Consider the 200 kHz frequency trade-off between size and efficiency. Verify that the 800 mA output capability meets peak load demands. Compare against non-synchronous alternatives if cost is critical, noting the efficiency difference at light loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC1504 family of low voltage synchronous regulators. It shares architectural similarities with other members like the LTC1504CS8 but differs in packaging and specific electrical tolerances. The series targets applications requiring efficient step-down conversion in space-constrained environments without the complexity of external driver circuits.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1507IS8#TRPBF offers similar buck functionality but with higher current capacity and different frequency characteristics. LTC1542CMS8#TRPBF is a comparator and not a direct functional replacement. Evaluate thermal performance and pin compatibility before substituting with other Analog Devices PMICs.
