2A Low Quiescent Current 1MHz High Efficiency
Synchronous Buck Regulator
ISL8012
The ISL8012 is a high efficiency, monolithic, synchronous
step-down DC/DC converter that can deliver up to 2A 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 ISL8012 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 240mV dropout voltage at 2A output
current. High 1MHz pulse width modulation (PWM) switching
frequency allows the use of small external components.
The ISL8012 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 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 ISL8012 offers a 1ms Power-good (PG) timer at power-up.
When shutdown, ISL8012 discharges the output capacitor. Other
features include internal soft-start, internal compensation,
overcurrent protection, and thermal shutdown.
The ISL8012 is offered in a space saving 3mmx3mm 10 Ld DFN
package lead free package with exposed pad lead frames for low
thermal. The complete converter occupies less than 0.35in 2
area.
