RT2613A
2.95V to 6V Input, 3A Output, 2MHz, Synchronous
Step-Down Converter
General Description
The RT2613A is a high efficiency step-down converter and
capable of delivering 3A output current over a wide input
voltage range from 2.95V to 6V.
The RT2613A provides accurate regulation for a variety of
loads with
±3%
accuracy. For reducing inductor size, it
provides up to 2MHz switching frequency. The efficiency
is maximized through the integrated 45mΩ MOSFETs
and 550μA typical supply current.
Under voltage lockout voltage of the RT2613A is 2.7V,
and it also provides external setting by a resistor network
on the enable pin.
The RT2613A provides protections such as inductor
current limit under voltage lockout and thermal shutdown.
The over temperature threshold is 145°C.
The RT2613A is available in WQFN-16L 3x3 package.
