LTC1435CG

DC DC Switching Controllers Overview

The LTC1435CG is a synchronous step-down switching regulator controller from Analog Devices, designed to drive external N-channel power MOSFETs. It operates with an input voltage range of 3.5V to 30V and supports a fixed switching frequency up to 400kHz. The device delivers a maximum output current of 2A with a single output configuration. Key electrical parameters include a quiescent current of 260µA and a minimum operating temperature of 0°C. It utilizes a current-mode control architecture in a PDSO16 package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., CG#PBF vs TRPBF) against the manufacturer's datasheet to confirm package type and temperature grade. Ensure compatibility with external MOSFET selection for the required current load. Confirm availability status as supply constraints may vary by region and distributor.

DC DC Switching Controllers Selection Notes

Select this component when a compact, high-efficiency buck controller is needed for low-to-medium current applications. Consider the 400kHz switching frequency for smaller passive components. Verify that the external MOSFETs can handle the thermal requirements at the target ambient temperature.

DC DC Switching Controllers Part Context

Part of the LTC1435 family, which includes variants like the LTC1435AIG and LTC1435CG. These controllers are designed for applications requiring efficient power conversion from higher input voltages to lower logic or analog supply rails.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible equivalents within the Analog Devices portfolio. Verify if alternative controllers offer similar current ratings and switching frequencies while meeting the same package and thermal specifications.
