TPS62740DSSR TI DC DC Switching Regulators

The TPS62740DSSR is an ultra-low-power synchronous step-down converter from Texas Instruments, offering a typical quiescent current of 360nA and up to 300mA output current. For selection, verify input voltage from 2.2V to 5.5V (start-up ≥2.15V), confirm output voltage set via four VSEL pins from 1.8V to 3.3V in 100mV steps, and note efficiency of up to 90% at 10µA output current. The DCS-Control™ topology ensures stable operation with a tiny 2.2µH inductor and 10µF output capacitor, achieving a total solution size under 31mm². Operating temperature ranges from -40°C to +85°C. Ideal for Bluetooth® Low Energy, Zigbee, and RF4CE devices, industrial metering, energy harvesting systems, wearable medical devices, wireless sensors, and battery-powered IoT applications requiring extended runtime.
