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-
