ETA2894 40V/3A, 9µA IQ, High Efficiency Synchronous Step-Down Converter DESCRIPTION The ETA2894 is a high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. The device operates with input voltage from 3.6V to 40V, making the ETA2894 ideal for wide input voltage range power conversion. ETA2894 adopts adjustable frequency current mode, the high frequency allows the use of small inductance value and low DCR inductors, thereby achieving higher space efficiencies. During light load, the converter goes into PFM mode that saves switching loss to achieve high power efficiency. ETA2894 is available in QFN3x4-24 package. FEATURES  Wide Input voltage range 3.
