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 cur-
rent 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 open-
drain low-side switch.
The E522.0x buck converter accommodates to common
single supply micro controller applications. Low exter-
nal component count and small QFN20L4 / TSSOP16
package allow compact PCB designs.
