TPS62740DSSR

Special Purpose Regulators Overview

The TPS62740DSSR is a Texas Instruments step-down DC/DC converter featuring a typical quiescent current of 360 nA. It operates with an input voltage range from 2.2 V to 5.5 V and provides a fixed output voltage selectable between 1.8 V and 3.3 V. The device supports up to 300 mA output current and utilizes a DCS-Control topology for high efficiency at light loads. It functions within a temperature range of -40°C to +85°C and is housed in a compact 12-pin WSON package.

Special Purpose Regulators Feature Summary

• Ultra-low static current of 360 nA enables extended battery life in portable applications.
• Integrated slew-controlled load switch allows power distribution to subsystems.
• Automatic transition to 100% duty cycle mode eliminates output ripple near full load.
• Optimized for small solution size using minimal external passive components.

Special Purpose Regulators Applications

• Bluetooth Low Energy (BLE) modules
• Zigbee wireless communication devices
• Industrial metering systems
• Energy harvesting circuits

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when sourcing. Confirm that the fixed output voltage variant matches the target system requirement, as other variants in the series offer adjustable outputs. Ensure compatibility with the required thermal management for the WSON-12 package during integration.

Special Purpose Regulators Selection Notes

Select this component for designs requiring minimal standby power consumption and small footprint constraints. It is suitable for single-cell lithium-ion or alkaline battery applications. Consider the integrated load switch feature if subsystem power sequencing is required without additional discrete components.

Special Purpose Regulators Part Context

This part belongs to the TPS6274x family of ultra-low IQ buck converters. It shares architectural similarities with the TPS62742 but differs in maximum output current capability. The series is designed specifically for RF-friendly operation and low noise requirements in space-constrained mobile electronics.

Special Purpose Regulators Replacement Considerations

The TPS62740DSST is a verified substitute offering identical electrical specifications with a different packaging format. Both parts share the same functional capabilities and pinout configuration for direct board-level replacement.
