ISL8018IRAJZ規(guī)格書詳情
The ISL8018 is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 8A 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, prebias start and
over-temperature protection, the ISL8018 offers a highly robust
power solution. It uses current control architecture to deliver fast
transient response and excellent loop stability.
The ISL8018 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 250mV dropout at 8A output current. Adjustable
frequency and synchronization allow the ISL8018 to be used in
applications requiring low noise.
The ISL8018 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 ISL8018 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
96.8mm2 area.
