Rev 1.00
May 5, 2011 6A Low Quiescent Current High Efficiency Synchronous Buck Regulator
The ISL8016 is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 6A
continuous output current from a 2.7V to 5.5V input supply.
The output voltage is adjustable from 0.6V to VIN. With an
adjustable current limit, reverse current protection, pre-bias
start and over temperature protection the ISL8016 offers a
highly robust power solution. It uses current control
architecture to deliver fast transient response and excellent
loop stability. Features The ISL8016 integrates a pair of low ON-resistance P-Channel
and N-Channel internal MOSFETs to maximize efficiency and
minimize external component count. 100% duty-cycle
operation allows less than 200mV dropout at 6A output
current. Adjustable frequency and synchronization allow the
ISL8016 to be used in applications requiring low noise.
Paralleling capability with phase interleaving allows the IC to
support >6A output current while offering reduced input and
output noise. Current Sharing Capable The ISL8016 can be configured for discontinuous or forced
continuous operation at light load. Forced continuous operation
reduces noise and RF interference while discontinuous mode …
