420kHz BUCK DC-DC CONVERTER
AP3005 420kHz fixed frequency buck (step-down) DC-DC converter, capable driving load with high efficiency, ripple excellent line load regulation. device includes voltage reference, oscillation circuit, error amplifier, internal PMOS etc. control circuit able adjust duty ratio linearly from 100%. enable function, over current protection function, short circuit protection function soft-start function built inside. When happens, operation frequency will reduced from 420kHz 40kHz. internal compensation block employed minimize external components. AP3005 serves ideal power supply unit portable devices, especially chip power portable systems. It's widely used PDVD, monitor chip powers. AP3005 available SOIC-8 package.
