4.5V to 24V Wide Input, Negative 5V/2A Output Non-synchronous Converter Reference Design


Design files


The PMP10680 reference design is a non-sync buck converter with buck-boost configuration. The PMP10680 accepts an input voltage of 4.5 to 24Vin and provides a negative 5V output capable of supplying continuous 2A of current to the load. With negative output and the self-positive input, this reference design could be used for bipolar amplifer/ADC/DAC supply. Internal compensation facilitates ease of use.
