RT6212C/D
2A, 18V, 800kHz, ACOT^TM Step-Down Converter
General Description
The RT6212C/D is a high-efficiency, monolithic
synchronous step-down DC-DC converter that can
deliver up to 2A output current from a 4.5V to 18V input
supply. The RT6212C/D adopts ACOT architecture to
allow the transient response to be improved and keep
in constant frequency. Cycle-by-cycle current limit
provides protection against shorted outputs and
soft-start eliminates input current surge during start-up.
Fault conditions also include output under-voltage
protection, output over-current protection, and thermal
shutdown.
