The RT5785A/B is a high-performance, Advanced Constant
On-Time (ACOTTM) monolithic synchronous step-down
DC/DC converter that can deliver up to 2A output current
from a 2.5V to 6V input supply. The proprietary ACOT
control architecture features quick transient response and
provides stable operation with small ceramic output
capacitors and without complicated external
compensation. The switching ripple voltage is easily
smoothed–out by small package filtering elements due
to a constant switching frequency of 1.5MHz and the
maximum duty cycle of 100% allows the device to operate
at low dropout use. With internal low on-resistance power
switches and extremely low quiescent current, the
RT5785A/B displays excellent efficiency and good behavior
across a range of applications.
Cycle-by-cycle current limit provides protection against
shorted outputs, input under-voltage lock-out, output
under-voltage protection, and thermal shutdown provide
safe and smooth operation in all operating conditions. The
RT5785A/B is available in the TSOT-23-8 (FC) package.
