LM536025QPWPRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LM536025QPWPRQ1 is an automotive-qualified synchronous step-down DC/DC converter from Texas Instruments. It operates with an input voltage range of 3.5 V to 36 V and provides a fixed 5 V output at up to 2 A. The device integrates a 200 kHz to 2.2 MHz adjustable switching frequency, enabling optimization for efficiency or transient response. It features low quiescent current of 27 uA and supports operation in PFM mode for light-load efficiency. The component is housed in a 16-pin HTSSOP package and is rated for junction temperatures up to 125°C, complying with AEC-Q100 standards.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'RQ1' indicates tape-and-reel packaging configuration. Confirm AEC-Q100 qualification grade matches project requirements. Ensure thermal management design accounts for 16-HTSSOP package limitations. Validate input/output capacitor selections against datasheet recommendations for stability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5 V output is required within the 3.5 V to 36 V input range. Compare against LM536025QPWPTQ1 if cut-tape packaging is preferred over reel. Consider LM536035QPWPRQ1 if higher 3 A output current is needed. Evaluate LM43602 variants if wider input voltage ranges beyond 36 V are necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM5360x-Q1 family of synchronous buck converters designed for automotive applications. It shares architectural similarities with LM53600, LM53601, and LM53603 series devices but offers distinct output current capabilities and fixed voltage options tailored for mid-power automotive loads.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM536025QPWPTQ1 serves as a direct functional substitute with identical electrical specifications but differs in packaging format (cut tape versus reel). Cross-reference LM53602AQPWPRQ1 for potential pin-compatible alternatives with adjusted feature sets.
