LMR36506RF3RPER

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36506RF3RPER is a synchronous step-down DC/DC converter from Texas Instruments, operating within a 3 V to 65 V input voltage range. It delivers a fixed 3.3 V output at up to 600 mA. The device features an adjustable switching frequency between 400 kHz and 2.2 MHz and maintains a low quiescent current of 4 uA. Packaged in a compact 9-VQFN-HR-9 format, it supports surface mount installation and functions reliably across a temperature range of -40°C to +150°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix RF3RPER against official datasheets to confirm pinout and thermal pad configuration. Ensure compatibility with moisture sensitivity level requirements during assembly. Cross-reference ordering part numbers with manufacturer documentation to avoid substitution errors due to packaging variations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when a wide input voltage range up to 65 V is required alongside a compact footprint. The adjustable frequency feature enables designers to balance electromagnetic interference filtering needs against external component size. Verify that the 600 mA output current meets the load requirements without exceeding thermal limits in the VQFN-HR-9 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR36506 series of ultra-small synchronous buck converters. It shares architectural similarities with other members like the LMR36506R3RPER but differs in specific ordering suffixes that may indicate tape and reel specifications or minor manufacturing lot variations. It serves as a power management IC for space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include LMR36506R3RPER for identical electrical performance with potential packaging differences. For automotive-grade requirements, consider the LMR36503-Q1 series, though output current and voltage settings differ. Always verify pin-to-pin compatibility and thermal characteristics before substituting.
