LTC3631IMS8E-5#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3631IMS8E-5#PBF is a high-efficiency, high-voltage synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 45 V and provides a fixed output voltage of 5 V at a maximum load current of 100 mA. The device features a typical quiescent current of 12 uA at no load while maintaining regulation. It utilizes an MSOP-8 package with an exposed pad for thermal management and supports adjustable switching frequencies. The component is rated for operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates internal high-side and synchronous power switches for efficient step-down conversion.
• Maintains low quiescent current consumption during light-load or no-load conditions.
• Features programmable peak current limit to optimize efficiency in lower current applications.

Voltage Regulators - DC DC Switching Regulators Applications

• High voltage battery-powered systems requiring efficient step-down regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the IMS8E designation matches the required MSOP-8 package variant. Ensure the -5 suffix corresponds to the fixed 5 V output requirement. Check current availability status as supply may be limited or subject to factory special orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a fixed 5 V output from high input voltages up to 45 V. The 100 mA output current capability suits low-power loads. Consider the MSOP-8 package size constraints and thermal requirements. Verify that the fixed output voltage meets system needs without external feedback adjustment.
