The APW7313 design with a current-mode control scheme, can convert wide input voltage of 4.5V to 24V to the output voltage adjust- able from 0.925V to 20V to provide excellent output volt- age 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, soft- start, and whole protections (over-temperature, and cur- rent-limit) into a single package. This device, available SOP-8P, provides a very compact system solution external components and PCB area.
