APW7337
3A 24V 340kHz synchronous Buck Converter
Features
General Description
• Wide Input Voltage from 4.5V to 24V
APW7337 is a 3A synchronous buck converter with inte-
• 3A Continuous Output Current
grated 85mΩ power MOSFETs. The APW7337 design
• Adjustable Output Voltage from 0.8V to 20V
with a current-mode control scheme, can convert wide
• Intergrated High/Low Side MOSFET
input voltage of 4.5V to 24V to the output voltage adjust-
• PFM/PWM mode Operation
• Fixed 340kHz Switching Frequency
able from 0.8V to 20V to provide excellent output voltage
regulation.
The APW7337 is equipped with an automatic PFM/PWM
• Stable with Low ESR Ceramic Output Capacitors _{mode operation. At light load, the IC operates in the PFM}
• Power-On-Reset Detection
mode to reduce the switching losses. At heavy load, the
• Programmable Soft-Start
IC works in PWM.
• Over-Temperature Protection
The APW7337 is also equipped with Power-on-reset, soft-
• Current-Limit Protection with Frequency Foldback ^{start, and whole protections (over-temperature, and cur-}
