HIGH FREQUENCY 2-PHASE, SINGLE OR DUAL OUTPUT SYNCHRONOUS STEP
DOWN CONTROLLER WITH OUTPUT TRACKING AND SEQUENCING
Description
The IR3623 IC integrates a dual synchronous
Buck controller, along with IP2003A it is providing
a high performance and flexible solution. The
IR3623 can be configured as 2-independent
outputs or as current share single output. The
current share configuration is ideal for high
current applications.
IR3623 enables output tracking and sequencing
of
multiple
rails in either ratiometric or
simultaneous fashion. The IR3623 features 180
o
out of phase operation which reduces the
required input/output capacitance and results to
few number of capacitor quantity. The switching
frequency is programmable from 200kHz to
1200kHz per phase using one external resistor, in
addition IR3623 also allows the switching
frequency to be synchronized to an external clock
signal. Other key features offered by this device
include two independent programmable soft
starts, two independent power good outputs,
precision enable input and under voltage lockout
function. The current limit is provided by sensing
the lower MOSFET's on-resistance for optimum
cost and performance. The output voltages are
monitored through dedicated pins protect against
open circuit and enhance faster response to an
overvoltage event.
