LMR23615DRRT

Voltage Regulators - DC DC Switching Regulators Overview

The LMR23615DRRT is a synchronous step-down DC-DC converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 4 V to 36 V and delivers up to 1.5 A of output current. The device supports adjustable output voltages between 1 V and 28 V. Key electrical parameters include a quiescent current of 75 uA and a switch frequency range of 200 kHz to 2.2 MHz. It functions within an operating temperature range of -40°C to +125°C and utilizes a WSON-12 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix DRRT corresponds to the WSON-12 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against specific manufacturing processes. Ensure the ordering part number matches the exact pinout and thermal pad specifications required by the design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1.5 A buck converter is needed with a wide 36 V input range. The adjustable frequency feature enables designers to trade off between external component size and electromagnetic interference performance. The WSON-12 package offers a small solution size suitable for space-constrained PCB layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR23615 series, which provides integrated power switches for simple design implementation. It is distinct from higher current variants like the LMR23630 or different package options such as the CDDAR series. The device represents a standard solution for mid-range current applications requiring robust performance.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include parts with identical pinouts but different current ratings or package types. Verify compatibility before swapping with other SIMPLE SWITCHER devices that may have different control loop characteristics.
