LMR23610ADDAR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR23610ADDAR is a SIMPLE SWITCHER® synchronous step-down DC-DC converter from Texas Instruments. It operates with an input voltage range of 4V to 36V and delivers a continuous output current of 1A. The device integrates a 400kHz switching frequency in PFM mode, achieving a minimum on-time of 60ns. It features peak current mode control for simplified loop compensation and includes internal compensation to minimize external components. Quiescent current is 75μA at no load, with a shutdown current of 2μA. Protection mechanisms include cycle-by-cycle current limiting, hiccup-mode short-circuit protection, and thermal shutdown. It is housed in an 8-pin HSOIC package with a PowerPAD.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ADDAR corresponds to the 8-PowerSOIC package with a PowerPAD when sourcing. Confirm that the ordering part number matches the required pinout and thermal pad configuration for your PCB layout. Ensure compatibility with the SIMPLE SWITCHER family design tools if utilizing WEBENCH for circuit validation before final procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a wide input voltage range up to 36V and a fixed 1A output capability. It is suitable for battery-powered systems due to low quiescent and shutdown currents. Consider the 8-pin HSOIC package constraints for thermal management. Evaluate the need for external clock synchronization or if the internal 400kHz PFM mode suffices for the target noise profile.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the SIMPLE SWITCHER family, designed for ease of use with minimal external components. It shares pin-to-pin compatibility with higher current variants like the LMR23625 (2.5A) and LMR23630 (3A), allowing for scalable PCB layouts within the same product line. The series emphasizes robust protection features and simplified control loop design for industrial and automotive environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LMR23625 and LMR23630 are pin-to-pin compatible alternatives offering higher output currents of 2.5A and 3A respectively. These can be used if increased load capacity is required without changing the PCB footprint. Verify thermal performance requirements when upgrading to higher current versions.
