RP6000

Preliminary RP6000 2A, 22V, 400kHz Step-Down Converter General Description The RP6000 is an asynchronous high voltage buck converter that can support the input voltage range from 4.75V to 22V and the output current can be up to 2A. Current Mode operation provides fast transient response and eases loop stabilization. The chip provides protection functions such as cycle-bycycle current limiting and thermal shutdown protection. In shutdown mode, the regulator draws 25µA of supply current. The RP6000 is available in a SOP-8 surface mount package. Ordering Information RP6000 Package Type S : SOP-8 Operating Temperature Range G : Green (Halogen Free with Commer- cial Standard) Note : Richtek Green products are : RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.
