The E522.01/02/03/04/05/06/07/08/09 product family provides ultra low quiescent current step down DC/DC converters with integrated power MOSFET.
The PFM (Pulse Frequency Modulation) regulator allows outstanding fast line- and load response time, stability and high efficiency over the full load current range. The integrated idle detection assures an ultra low idle current and high efficiency with low load currents down to <100μA for the completely powered application. A power-good signal is provided by a high-voltage opendrain low-side switch. The E522.0x buck converter accommodates to common single supply micro controller applications. Low external component count and small QFN20L4 / TSSOP16 package allow compact PCB designs.
