LMR36502PS5RPER

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36502PS5RPER is a synchronous step-down DC/DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 65 V and provides a fixed output voltage of 5 V at a maximum output current of 150 mA. The device features a low quiescent current of 1 uA and supports adjustable switching frequencies from 200 kHz to 2.2 MHz. It is housed in a compact VQFN-HR-9 package and functions within a temperature range of -40°C to +150°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Supports high input voltages up to 65 V for flexible power distribution

• Compact VQFN-HR-9 package enables space-constrained designs
• Integrated synchronous rectification improves conversion efficiency

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial automation control systems
• Automotive infotainment and sensor modules
• Portable battery-powered instrumentation
• Point-of-load regulation for digital circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PS5RPER to confirm the fixed 5 V output configuration and reel packaging type. Ensure compatibility with the required thermal management for the VQFN-HR-9 package under maximum load conditions. Confirm moisture sensitivity level handling procedures during assembly to prevent package damage.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a wide input voltage range up to 65 V. The 150 mA current rating suits low-power applications where size is critical. Consider the adjustable frequency feature for optimizing EMI or transient response requirements compared to fixed-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR36502 family of ultra-small synchronous buck converters. It shares the same core topology and package as variants like LMR36502P3RPER, differing primarily in the fixed output voltage setting. The series is designed for high-efficiency power management in compact electronic devices.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR36502P3RPER offers a similar form factor but provides a fixed 3.3 V output instead of 5 V. Designers requiring different voltage levels should verify pin compatibility and thermal performance before substitution.
