LM43602QPWPRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LM43602QPWPRQ1 is an automotive-qualified synchronous step-down DC-DC converter from Texas Instruments. It operates with an input voltage range of 3.5V to 60V and delivers up to 2A of output current. The device features a fixed 2.1MHz switching frequency and adjustable output voltage between 1V and 28V. It utilizes peak current mode control for simplified compensation and includes integrated soft-start, power good indication, and thermal shutdown. The component is housed in a 16-pin HTSSOP package and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'PWPRQ1' corresponds to the HTSSOP-16 package and tape-and-reel quantity required for your assembly line. Confirm the AEC-Q100 qualification status matches your OEM's quality requirements. Ensure compatibility with your PCB footprint design for the 16-pin PowerTSSOP outline before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive applications requiring a wide input voltage range up to 60V. It is suitable for systems needing a fixed high-frequency switching solution to minimize passive component size. Consider this part if AEC-Q100 certification is mandatory and a 2A continuous output current is sufficient for the target load.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM4360x family of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM43602DSUR but differs in automotive qualification and maximum input voltage capabilities. The family emphasizes ease of use with minimal external components while maintaining high efficiency and compact form factors for modern electronic designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other AEC-Q100 qualified buck converters from Texas Instruments such as the LM53602 series or LM46002 series, provided they meet the 60V input requirement. Verify pin-to-pin compatibility and thermal characteristics when transitioning between different package types or current ratings within the manufacturer's portfolio.
