The ISL8120IRZEC integrates two voltage-mode
synchronous buck PWM controllers to control a dual
independent voltage regulator or a 2-phase single output
regulator. It has PLL circuits and can output a phase-shiftprogrammable
clock signal for the system to be expanded to
3-, 4-, 6-, 12- phases with desired interleaving phase shift. It
also integrates current sharing control for the power module
to operate in parallel, which offers high system flexibility.
It has voltage feed forward compensation to maintain a
constant loop gain for optimal transient response, especially
for applications with a wide input voltage range. Its
integrated high speed MOSFET drivers and multi-feature
functions provide complete control and protection for a
2/n-phase synchronous buck converter, dual independent
regulators, or DDR tracking applications (VDDQ and VTT
outputs).
