APW7336
2A 24V 340kHz synchronous Buck Converter
Features
General Description
Wide Input Voltage from 4.5V to 24V
APW7336 is a 2A synchronous buck converter with inte-
2A Continuous Output Current
grated power MOSFETs. The APW7336 design with a cur-
Adjustable Output Voltage from 0.8V to 20V
rent-mode control scheme, can convert wide input volt-
Intergrated High/Low Side MOSFET
age of 4.5V to 24V to the output voltage adjustable from 0.
PFM/PWM mode Operation
Fixed 340kHz Switching Frequency
8V to 20V to provide excellent output voltage regulation.
The APW7336 is equipped with an automatic PFM/PWM
mode operation. At light load, the IC operates in the PFM
Stable with Low ESR Ceramic Output Capacitors mode to reduce the switching losses. At heavy load, the
Power-On-Reset Detection
IC works in PWM.
Programmable Soft-Start
The APW7336 is also equipped with Power-on-reset, soft-
Over-Temperature Protection
start, soft-stop, and whole protections (under-voltage,
Current-Limit Protection with Frequency Foldback over-temperature, and current-limit) into a single package.
Enable/Shutdown Function
This device, available TDFN3x3-10, provides a very com-
Small TDFN3x3-10 Packages

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 “Green” to 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).
