The ISL8014 is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 4A
continuous output current from a 2.7V to 5.5V input supply. It
uses a current control architecture to deliver very low duty
cycle operation at high frequency with fast transient
response and excellent loop stability.
The ISL8014 integrates a pair of low ON-resistance
P-Channel and N-Channel internal MOSFETs to maximize
efficiency and minimize external component count. The
100% duty-cycle operation allows less than 400mV dropout
voltage at 4A output current. High 1MHz pulse-width
modulation (PWM) switching frequency allows the use of
small external components and SYNC input enables multiple
ICs to synchronize out of phase to reduce ripple and
eliminate beat frequencies.
