4A Low Quiescent Current 1MHz High Efficiency

Synchronous Buck Regulator

ISL8014

Features

• High Efficiency Synchronous Buck Regulator with up

to 97% Efficiency

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.

• Power-Good (PG) Output with a 1ms Delay

• 2.7V to 5.5V Supply Voltage

• 3% Output Accuracy Over-Temperature/Load/Line

• 4A Output Current

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.

• Pin Compatible to ISL8013

• Start-up with Pre-Biased 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 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.

• 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 over voltage 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)

Applications

• DC/DC POL Modules

The ISL8014 is offered in a space saving 4x4 QFN lead

free package with exposed pad lead frames for low

thermal.

• µC/µP, FPGA and DSP Power

• Plug-in DC/DC Modules for Routers and Switchers

• Portable Instruments

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.

• Test and Measurement Systems

• Li-ion Battery Powered Devices

• Small Form Factor (SFP) Modules

• Bar Code Readers

The ISL8014 is offered in a 16 Ld 4mmx4mm QFN

package with 1mm maximum height. The complete

converter occupies less than 0.4in area.
