TPS82740 DC-DC Step-Down Converters Texas Instruments TPS82740 DC-DC Step-Down Converters are the industry's first step-down converter module featuring typically 360nA quiescent current consumption. It is a complete MicroSIPTM 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 6.7mm2. This new DCS-Control™ based device extends the light load efficiency range below 10µA load currents. It supports output currents up to 200mA. The device operates from rechargeable Li-Ion batteries, Li-primary battery chemistries such as Li-SOCl2, Li-MnO2 and two or three-cell alkaline batteries. The input voltage range up to 5.5V also allows operation from a USB port and thin-film solar modules. The TPS82740AEVM-617 is designed to help the user easily evaluate and test the operation and functionality of the Fully Integrated TPS82740A Power Module.
