LM46002PWPR

Voltage Regulators - DC DC Switching Regulators Overview

The LM46002PWPR is a synchronous step-down voltage converter from Texas Instruments, operating with an input voltage range of 3.5 V to 60 V and delivering up to 2 A of output current. It provides an adjustable output voltage between 1 V and 28 V through a single output channel. The device features a fixed switching frequency of 2.2 MHz and maintains a low quiescent current of 27 uA. It supports operation across a temperature range of -40°C to +125°C and utilizes a 16-pin HTSSOP package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'PWPR' indicates the tape-and-reel packaging variant distinct from tube-packaged versions like 'PWP'. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the automotive qualification is not required unless specified by the '-Q1' designation, as this standard version lacks AEC-Q100 certification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is necessary alongside moderate current demands. The fixed 2.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the HTSSOP-16 thermal performance for your PCB layout. This part is suitable for general-purpose DC-DC conversion where automotive reliability standards are not mandated.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the SIMPLE SWITCHER family of power management ICs. It shares architectural similarities with the LM46000 (0.5 A) and LM46001 variants but offers higher current capacity. It serves as a non-isolated step-down solution within Texas Instruments' portfolio of integrated power stages designed for compact designs.
