The APW8804, design with a current-mode control scheme, can convert wide input voltage of 2.
6V to 6V to the output voltage adjustable from 0.
6V to 6V to provide excellent output voltage regulation.
The APW8804 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 mode.
At PWM mode, the switching frequency is set by the external resistor.
The APW8804 is also equipped with Power-on-reset, softstart, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package.
This device, available TDFN3x3-10 and SOP-8P, provides a very compact system solution external components and PCB area.
