DATASHEET  
4A Low Quiescent Current 1MHz High Efficiency  
Synchronous Buck Regulator  
ISL8014A  
Features  
The ISL8014A 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.  
• High efficiency synchronous buck regulator with up to 97%  
efficiency  
• Power-good (PG) output with a 1ms delay  
• 2.8V to 5.5V supply voltage  
• 3% output accuracy over-temperature/load/line  
• 4A output current  
The ISL8014A 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 for use of small external  
components and the SYNC input enables multiple ICs to  
synchronize out-of-phase to reduce ripple and eliminate beat  
frequencies.  
• Pin compatible to ISL8013A  
• Start-up with prebiased output  
• Internal soft-start - 1ms  
• Soft-stop output discharge during disabled  
• 35µA quiescent supply current in PFM mode  
• Selectable forced PWM mode and PFM mode  
• External synchronization up to 4MHz  
• Less than 1µA logic controlled shutdown current  
• 100% maximum duty cycle  
The ISL8014A 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.  
• Internal current mode compensation  
• Peak current limiting and hiccup mode short-circuit  
protection  
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.  
• Over-temperature protection  
• Small 16 Ld 4mmx4mm QFN  
• Pb-Free (RoHS compliant)  
The ISL8014A is offered in a space saving 4mmx4mm QFN,  
lead free package with exposed pad lead frames for low  
thermal resistance.  
Applications  
• DC/DC POL modules  
• µC/µP, FPGA and DSP power  
• Plug-in DC/DC modules for routers and switchers  
• Portable instruments  
The ISL8014A offers a 1ms power-good (PG) timer at  
power-up. When shutdown, ISL8014A discharges the output  
capacitor. Other features include internal soft-start, internal  
compensation, overcurrent protection, and thermal shutdown.  
• Test and measurement systems  
• Li-ion battery powered devices  
• Small form factor (SFP) modules  
• Barcode readers  
The ISL8014A is offered in a 16 Ld 4mmx4mm QFN package  
with 1mm maximum height. The complete converter occupies  
less than 0.4in area.
