LOW QUIESCENT CURRENT PFM STEP DOWN CONVERTERS PRODUCTION DATA - AUG 13, 2015 Features General Description Wide input voltage range 4.5V to 40V The E522.01/02/03/04/05/06/07/08/09 product family PFM regulator up to 1.33MHz provides ultra low quiescent current step down DC/DC Up to >92% efficiency converters with integrated power MOSFET. Very low 8A sleep mode current The PFM (Pulse Frequency Modulation) regulator allows Ultra low 12A standby current outstanding fast line- and load response time, stability 100% duty cycle capability and high efcfi iency over the full load current range. The Small QFN20L4 lead-less package integrated idle detection assures an ultra low idle cur- TSSOP16 package rent and high efcfi iency with low load currents down AEC-Q100 qualification to <100A for the completely powered application. A Junction temperature range -40C to +150C power-good signal is provided by a high-voltage open- drain low-side switch. The E522.0x buck converter accommodates to common Applications single supply micro controller applications. Low exter- Micro Controller Systems nal component count and small QFN20L4 / TSSOP16 Automotive Telematics, Dashboards package allow compact PCB designs.
