LMR36506RFRPER

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36506RFRPER is a synchronous step-down DC/DC converter from Texas Instruments, operating within an input voltage range of 3 V to 65 V. It delivers a maximum output current of 600 mA with a fixed output voltage of 1 V. The device features a low quiescent current of 4 μA and supports switching frequencies between 400 kHz and 2.2 MHz. It operates reliably across a temperature range of -40°C to +150°C and is housed in a compact VQFN-HR-9 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Ultra-small form factor utilizing VQFN-HR-9 packaging for space-constrained designs
• High input voltage capability up to 65 V for broad system compatibility
• Low static current consumption of 4 μA for efficient power management

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring high-voltage input regulation
• Automotive electronics operating within extended temperature ranges
• Portable devices needing efficient step-down conversion from higher bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix RFRPER confirms the fixed 1 V output configuration, as other variants in the LMR36506 series offer adjustable or different fixed outputs. Ensure the VQFN-HR-9 package type matches your PCB footprint requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1 V output is required from a wide input voltage range up to 65 V. The 600 mA current rating suits moderate load applications. Consider the 400 kHz to 2.2 MHz frequency range for balancing efficiency and external component size. The -40°C to +150°C operating range makes it suitable for harsh environments compared to standard commercial grade parts.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR36506 family of ultra-small synchronous buck converters. The family shares common core architectures but varies by output voltage configuration and package options. The LMR36506RFRPER specifically denotes the version with a fixed 1 V output, distinguishing it from adjustable (RRPER) or other fixed voltage variants like the 3.3 V version.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LMR36506 variants such as LMR36506RRPER for adjustable output needs, provided the fixed 1 V requirement can be met via external resistor dividers if compatible. Verify pinout and thermal characteristics match exactly when considering cross-series replacements.
