DATASHEET
ISL78214
4A Low Quiescent Current High Efficiency Synchronous Buck Regulator
The
ISL78214
is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 4A
continuous output current from a 2.8V 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 ISL78214 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, that can be synchronization up to 4MHz
with an external clock, 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 ISL78214 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 overvoltage comparator and over-temperature monitor
circuit. A power-good output voltage monitor indicates when
the output is in regulation.
The ISL78214 is offered in a space saving 4x4 QFN lead free
package with exposed pad lead frames for low thermal.
The ISL78214 offers a 1ms Power-good (PG) timer at
power-up. When shutdown, ISL78214 discharges the output
capacitor. Other features include internal soft-start, internal
compensation, overcurrent protection and thermal shutdown.
The ISL78214 is offered in a 16 Ld 4mmx4mm QFN package
with 1mm maximum height. The complete converter occupies
less than 0.4in
2
area.
The ISL78214 is AEC-Q100 qualified. The ISL78214 is rated
for the automotive temperature range -40°C to +105°C.
