Preliminary
RP6001
3A, 24V, 400kHz Step-Down Converter
General Description
The RP6001 is a high voltage buck converter that can
support the input voltage range from 4.75V to 24V and
the output current can be up to 3A. Current Mode operation
provides fast transient response and eases loop
stabilization.
The chip provides protection functions such as cycle-by-
cycle current limiting and thermal shutdown protection.
In shutdown mode, the regulator draws 25µA of supply
current. The RP6001 is available in a SOP-8 (Exposed
Pad) surface mount package.
