TPS82740A Datasheet | Texas Instruments

Features - 1 360-n A Typical Quiescent Current - Up to 90% Efficiency at 10-µA Output Current - Pin-Selectable Output Voltages in 100-m V Steps - Integrated Slew Rate Controlled Load Switch - Up to 200-m A Output Current - Input Voltage Range VIN from 2.2 V to 5.5 V - RF Friendly DCS-Control™ - Low Output Voltage Ripple - Automatic Transition to No Ripple 100% Mode - Discharge Function on VOUT and LOAD - Sub 1.1-mm Profile Solution - Total Solution Size < 6.7mm2 - Small 2.3 mm × 2.9 mm Micro SIP™ Package 2 Applications - Bluetooth® Low Energy, RF4CE, Zigbee - Wearable Electronics - Energy Harvesting 3 Description The TPS82740 is the industry's first step-down converter module featuring typically 360-n A quiescent current consumption. It is a plete Micro SIPTM DC/DC step-down power solution intended for ultra low-power applications. The module includes the switching regulator, inductor and input/output capacitors. The integration of all required passive ponents enables a tiny solution size of only 6.7 mm2. Figure 1.
