ISL8014 NOT RECOMMENDED FOR NEW DESIGNS
RECOMMENDED REPLACEMENT PART
ISL8014A DATASHEET 4A Low Quiescent Current 1MHz High Efficiency Synchronous Buck Regulator
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. Features 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. 4A Output Current The ISL8014 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. …
