LTC1625IGN#TRPBF

DC DC Switching Controllers Overview

The LTC1625IGN#TRPBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.7V to 36V and drives external N-channel power MOSFETs. The device utilizes current mode control with VDS sensing, eliminating the need for a sense resistor. It features a fixed switching frequency of 150kHz and supports output voltages down to 0.8V. The component is housed in a 16-lead SSOP package and is designed for efficient DC-to-DC conversion applications.

DC DC Switching Controllers Feature Summary

• General-purpose DC/DC conversion systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact pinout and electrical specifications required for your design. Cross-reference with official datasheets to validate compatibility with your system requirements before procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring high efficiency without the cost and board space of a sense resistor. It is suitable for applications with input voltages up to 36V. Consider the 150kHz frequency for balancing size and efficiency. Ensure external MOSFETs are compatible with the drive capabilities and that the thermal design accommodates the expected load conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC1625 family of synchronous buck regulators. It is distinct from other LTC series controllers by its specific VDS-based current sensing architecture. The IGN#TRPBF designation specifies the industrial temperature grade and reel packaging format, differentiating it from tube-packaged or commercial-grade variants.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other Analog Devices synchronous buck controllers with similar VDS sensing features. Verify pin compatibility and electrical parameters such as input voltage range and switching frequency. Alternative parts may require changes to the external MOSFET selection or compensation network.
