Texas Instruments' TPS82740 is the industry’s first step-down converter module featuring typically 360 nA quiescent-current consumption. It is a complete MicroSIP 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 components enables a tiny solution size of only 6.7 mm². This new DCS-Control™-based device extends the light-load efficiency range below 10 µA load currents. It supports output currents up to 200 mA.
Applications include Bluetooth low energy, RF4CE, ZigBee, wearable electronics, and energy harvesting.
