LTC3622IMSE-2#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3622IMSE-2#TRPBF is a dual synchronous step-down regulator from Analog Devices, housed in a 16-lead MSOP package. It integrates two independent buck converters, each delivering up to 1A of output current. The device operates from an input voltage range of 2.7V to 17V and supports adjustable output voltages between 600mV and 1.7V per channel. It features a fixed switching frequency of 2.25MHz with ±50% synchronization capability. Quiescent current is specified at 5µA during operation and 3mA in standby. The unit functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the IMSE-2 designation matches the required 2.25MHz switching frequency variant. Ensure the 16-lead MSOP footprint aligns with the target PCB layout. Cross-reference the datasheet revision date to ensure compatibility with latest thermal guidelines.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated or coupled outputs are needed from a single IC. The 2.25MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 1A per channel rating meets the peak load requirements of both rails. Consider the MSOP package thermal performance for the intended ambient operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3622 family of dual synchronous step-down regulators. It shares core architecture with variants like the LTC3622HDE-2 but differs in package type and switching frequency. The IMSE-2 specifically denotes the MSOP package with the higher 2.25MHz fixed frequency option.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LTC3622IMSE-2#PBF offers the same electrical specifications in tube packaging instead of tape-and-reel.
