Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package designation matches the HTSSOP-16 (PowerTSSOP) configuration required for your PCB footprint. Confirm that the suffix indicates the standard commercial or automotive grade variant as specified in the official datasheet. Ensure compatibility with your manufacturing process regarding moisture sensitivity levels and reflow profiles. Cross-reference the ordering part number against the manufacturer's latest release notes to avoid obsolete or discontinued revisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2 A synchronous buck converter is required with an input voltage up to 36 V. The adjustable output range accommodates various logic and analog supply rails. Consider the thermal performance of the 16-pin package for your specific layout constraints. Evaluate the switching frequency setting against external inductor and capacitor selection requirements to meet ripple specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM43602 series, which includes variants like LM43602DSUR and LM43602AQPWPTQ1. These parts share core electrical characteristics but differ in package type and qualification standards. The PWPT suffix specifically denotes the HTSSOP-16 package format. This series is designed for high-efficiency power management in space-constrained applications requiring robust performance.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM43602DSUR offers identical electrical specifications in a SON-16 package. LM43602AQPWPTQ1 provides the same functionality with AEC-Q100 automotive qualification in the same HTSSOP-16 package. Verify pinout compatibility and thermal dissipation differences when substituting between package types.
