APW7313 3A 24V 340kHz synchronous Buck Converter Features Wide Input Voltage from 4.5V to 24V 3A Continuous Output Current Adjustable Output Voltage from 0.925V to 20V Intergrated High/Low Side MOSFET PFM/PWM mode Operation Fixed 340kHz Switching Frequency Stable with Low ESR Ceramic Output Capacitors Power-On-Reset Detection Programmable Soft-Start Over-Temperature Protection Current-Limit Protection with Frequency Foldback Enable/Shutdown Function Small SOP-8P Package Lead Free and Green Devices Available (RoHS Compliant) General Description APW7313 is a 3A synchronous buck converter with integrated 110mΩ power MOSFETs. The APW7313 design with a current-mode control scheme, can convert wide input voltage of 4.5V to 24V to the output voltage adjustable from 0.925V to 20V to provide excellent output voltage regulation. The APW7313 is equipped with an automatic PFM/PWM mode operation. At light load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM. The APW7313 is also equipped with Power-on-reset, softstart, and whole protections (over-temperature, and current-limit) into a single package. This device, available SOP-8P, provides a very compact system solution external components and PCB area.
