RT6213A/B
3A Peak, 18V, 500kHz, ACOTTM Step-Down Converter
General Description
Features
Integrated 150m/70m MOSFETs
4.5V to 18V Supply Voltage Range
500kHz Switching Frequency
ACOT Control
The RT6213A/B is a high-efficiency, monolithic
synchronous step-down DC/DC converter that can
deliver up to 3A peak output current from a 4.5V to 18V
input supply. The RT6213A/B 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.
