General Description

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.
