LM43600QPWPRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LM43600QPWPRQ1 is an automotive-qualified synchronous buck converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 3.5V to 36V and delivers a maximum output current of 500mA. The device features adjustable output voltage from 1V to 28V and supports programmable switching frequencies between 200kHz and 2.2MHz. Packaged in a 16-pin HTSSOP, it includes integrated soft-start, power good indication, and protection against over-temperature, UVLO, and short circuits.

• Telematics units and connectivity interfaces

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct package type and tape-and-reel quantity. Confirm AEC-Q100 qualification status if automotive compliance is mandatory. Check for recent Product Change Notifications regarding assembly or material updates. Ensure compatibility with existing PCB footprints for the 16-HTSSOP package. Validate supply chain authenticity through authorized distributors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, automotive-rated solution is needed for low-to-medium current applications. The 500mA output capability suits subsystems rather than main power rails. Consider the wide input voltage range for battery-backed or alternator-fed systems. Evaluate the need for programmable frequency to minimize passive component footprint. Compare against higher-current variants like the LM43601 or LM43602 if load requirements exceed 500mA.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM4360x series of synchronous step-down converters designed for simplicity and efficiency. It shares architectural similarities with the LM43601 and LM43602 but differs primarily in maximum output current ratings. The series utilizes peak current mode control for straightforward compensation and fast transient response. It is positioned as a drop-in replacement for older generation regulators in automotive infotainment and body electronics.
