3A Low Quiescent Current, High Efficiency
Synchronous Buck Regulator
ISL78213
The ISL78213 is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 3A 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 ISL78213 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 300mV dropout voltage at 3A output
current. High 1MHz pulse-width modulation (PWM) switching
frequency, that can be synchronized 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 ISL78213 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 ISL78213 is offered in a space saving 4x4 QFN lead free
package with exposed pad lead frames for low thermal
resistance.
The ISL78213 includes 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 300mV dropout voltage at 3A.
The ISL78213 offers a 1ms Power Good (PG) timer at power-up.
When shutdown, ISL78213 discharges the output capacitor.
Other features include internal soft-start, internal compensation,
overcurrent protection, and thermal shutdown.
The ISL78213 is offered in a 4mmx4mm 16 Ld QFN package
with 1mm maximum height. The complete converter occupies
less than 0.4in 2 area.
The ISL78213 is AEC-Q100 rated. The ISL78214 is rated for the
automotive temperature range (-40°C to +105°C).
