ISL8014
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.
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.
Fault protection is provided by internal hiccup mode
current limiting during short circuit and overcurrent
conditions, an output over voltage comparator and
over-temperature monitor circuit. A power good output
voltage monitor indicates when the output is in
regulation.
The ISL8014 is offered in a space saving 4x4 QFN lead
free package with exposed pad lead frames for low
thermal.
The ISL8014 offers a 1ms Power-Good (PG) timer at
power-up. When shutdown, ISL8014 discharges the
output capacitor. Other features include internal
soft-start, internal compensation, overcurrent protection,
and thermal shutdown.
The ISL8014 is offered in a 16 Ld 4mmx4mm QFN
package with 1mm maximum height. The complete
converter occupies less than 0.4in 2 area.
