ISL8016
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 V
IN
. 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.
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.
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
provides high efficiency by reducing switching losses at light
loads.
The ISL8016 is offered in a space saving 20 Ld 3x4 QFN lead
free package with exposed pad lead frames for excellent
thermal performance. The complete converter occupies less
than 0.15in
2
area.
Various fixed output voltages are available upon request. See
Ordering Information on page 2 for more detail.
