APW7309
24V 2A 500kHz Synchronous Buck Converter
Features
General Description
Wide Input Voltage from 4.7V to 24V
APW7309 is a 2A synchronous buck converter with inte-
2A Continuous Output Current
grated low RDS(ON) power MOSFETs. The APW 7309
Adjustable Output Voltage from 0.807V to 13V
design with a current-mode control scheme, can convert
Integrated Low RDS(ON) MOSFETs
Fixed 500kHz Switching Frequency
wide input voltage of 4.7V to 24V to the output voltage
adjustable from 0.807V to 13V to provide excellent output
voltage regulation.
Stable with Low ESR Ceramic Output Capacitors The APW7309 is equipped advance asynchronous modu-
Power-On-Reset Detection
lation mode operation. Increase efficiency at light load.
Over-Temperature Protection
The APW7309 is also equipped with Power-on-reset, soft
Current-Limit Protection with HICCUP Mode
start, and whole protections (under-voltage,
Small TSOT-23-8A Package
over-temperature, and current-limit) into a single package.
Lead Free and Green Devices Available
(RoHS Compliant)
This device, available TSOT-23-8A, provides a very com-
pact system solution external components and PCB area.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
