DESCRIPTION
The IR3823 SupIRBuck
®
is a 3A easy-to-use, fully
integrated and highly efficient synchronous Buck
regulator
intended
for
Point-Of-Load
(POL)
applications.
The IR3823 features programmable switching
frequency from 300kHz to 1.5MHz, three selectable
soft-start time options, and smooth synchronization to
an external clock. The IR3823 uses voltage mode
control employing a proprietary PWM modulator,
allowing high control bandwidth and fast loop response
with less output capacitors. The other important
functions include thermally compensated over current
protection, output over voltage protection and thermal
shut-down, etc.
The IR3823 is offered in a small
3.5mm x 3.5mm PQFN package with excellent thermal
performance.
