TPS40042DRCR

DC DC Switching Controllers Overview

The TPS40042DRCR is a low pin count, low input voltage synchronous buck DC-DC controller manufactured by Texas Instruments. It operates within an input voltage range of 3.0 V to 5.5 V and supports output voltages down to 600 mV. The device features a compact VSON-10 (3x3 mm) package with exposed pad for efficient thermal performance. Designed for applications requiring minimal external component count, it integrates essential control functions for step-down conversion.

DC DC Switching Controllers Feature Summary

• Low pin count architecture simplifies board layout and reduces external component requirements
• Supports low input voltage operation suitable for battery-powered and portable systems
• Integrated synchronous rectification improves efficiency at light and heavy loads

DC DC Switching Controllers Applications

• Portable consumer electronics
• Battery-powered devices
• Point-of-load regulation in communication equipment

DC DC Switching Controllers Procurement Notes

Verify the exact ordering suffix DRCR corresponds to the VSON-10 package variant. Confirm moisture sensitivity level and reflow soldering profile compliance with JEDEC standards. Ensure ESD handling procedures are followed during assembly due to the small form factor and exposed thermal pad design.

DC DC Switching Controllers Selection Notes

Select this controller when a minimal pin count and low input voltage range are required. It is suitable for designs prioritizing space efficiency over high power output. Compare against other TPS40xxx series parts if higher current or wider input voltage ranges are needed.

DC DC Switching Controllers Part Context

Part of the TPS40xxx family of synchronous buck controllers from Texas Instruments, designed for low-voltage, low-pin-count applications. The DRCR suffix denotes the specific VSON-10 package configuration used in compact PCB layouts.

DC DC Switching Controllers Replacement Considerations

TPS40040DRBR offers similar functionality but with different electrical characteristics and package options. Verify compatibility with existing bill of materials before substitution.
