10A output 1-5V low voltage high current converter

APW7057 main performance
  (1) Input working power supply voltage is 5V.
  (2) The 0.8V reference source inside the chip has an accuracy of ±1.5% within all linear adjustments, load adjustments and temperature ranges.
  (3) The output voltage range is 0.8V~VCC.
  (4) The duty cycle adjustment range is 0~100%.
  (5) It has the internal loop compensation function of the chip.
  (6) It has a soft start function, and its typical soft start time is 2ms.
  (7) It has over-current protection function. In order to reduce costs, the current sensing resistor can use the on-resistance RDS of the MOSFET power switch.
  (8) It has under-voltage protection and shutdown control functions.
  (9) Can drive external N-MOSFET power switch.
  (10) It has a very space-saving SOP-8 type package.

  (11) Product series with operating junction temperature ranging from 0 to 125°C are available.
