The ISL6244 provides core-voltage regulation by driving 2 to

4 interleaved synchronous-rectified buck-converter channels

in parallel. Interleaving the channel timing results in

increased ripple frequency which reduces input and output

ripple currents. The reduction in ripple results in lower

component cost, reduced dissipation, and a smaller

implementation area.

The ISL6244 uses cost and space-saving r

DS(ON)

sensing

for channel current balance, active voltage positioning, and

over-current protection. Output voltage is monitored by an

internal differential remote sense amplifier. A high-bandwidth

error amplifier drives the output voltage to match the

programmed 5-bit DAC reference voltage. The resulting

compensation signal guides the creation of pulse width

modulated (PWM) signals to control companion Intersil

MOSFET drivers. The OFS pin allows direct offset of the

DAC voltage from 0V to 100mV using a single external

resistor. The entire system is trimmed to ensure a system

accuracy of ± 1%.

Outstanding features of this controller IC include

Dynamic VID

technology allowing seamless on-the-fly VID

changing without the need of any external components.

Battery “feed-forward” is provided to allow for traditional

control schemes over total input voltage variation. Output

voltage “droop” or active voltage positioning is optional.

When employed, it allows the reduction in size and cost of

the output capacitors required to support load transients. A

threshold-sensitive enable input allows the use of an

external resistor divider for start-up coordination with Intersil

MOSFET drivers or any other devices powered from a

separate supply.

Superior over-voltage protection is achieved by gating on the

lower MOSFET of all phases to reduce the output voltage.

Under-voltage conditions are detected, but PWM operation

is not disrupted. Over-current conditions cause a hiccup-

mode response as the controller repeatedly tries to restart.

After a set number of failed startup attempts, the controller

latches off. A power good logic signal indicates when the

converter output is between the UV and OV thresholds.
