LOW POWER STEP DOWN CONVERTER
PRELIMINARY INFORMATION - AUG 17, 2012
Features
General Description
ÿ Wide input voltage range 4.5V to 40V
ÿ PFM regulator up to 1.33MHz
ÿ Up to >92% efficiency
The E522.71/72/73/74/75/76/77/78/79 product family
provides ultra low quiescent current step down DC/DC
converters with integrated power MOSFET.
ÿ Very low 8µA sleep mode current
ÿ Ultra low 12µA standby current
ÿ 100% duty cycle capability
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 E522.7x buck converter accommodates to common
single supply micro controller applications. Low exter-
nal component count and small exposed die pad SOIC
8-EP package allow compact PCB designs.
ÿ SOIC8-EP package
ÿ Ambient temperature range up to +105°C
