6A Low Quiescent Current High Efficiency Synchronous

Buck Regulator

ISL8016

Features

The ISL8016 is a high efficiency, monolithic, synchronous

step-down DC/DC converter that can deliver up to 6A continuous

output current from a 2.7V to 5.5V input supply. The output

• High Efficiency Synchronous Buck Regulator with up to 97%

Efficiency

• 1% Reference Accuracy Over-Temperature/Load/Line

• Fixed Output Voltage Option

voltage is adjustable from 0.6V to V . With an adjustable current

limit, reverse current protection, pre-bias start and over

temperature protection the ISL8016 offers a highly robust power

solution. It uses current control architecture to deliver fast

transient response and excellent loop stability.

• ±10% Output Voltage Margining

• Adjustable Current Limit

• Current Sharing Capable

The ISL8016 integrates a pair of low ON-resistance P-Channel

and N-Channel internal MOSFETs to maximize efficiency and

minimize external component count. 100% duty-cycle operation

allows less than 200mV dropout at 6A output current. Adjustable

frequency and synchronization allow the ISL8016 to be used in

applications requiring low noise. Paralleling capability with

phase interleaving allows the IC to support >6A output current

while offering reduced input and output noise.

• Start-up with Pre-Biased Output

• Internal Soft-Start - 1ms or Adjustable, Internal/External

Compensation

• Soft-Stop Output Discharge During Disabled

• Adjustable Frequency from 500kHz to 4MHz - Default at 1MHz

• External Synchronization up to 4MHz - Master to Slave Phase

Shifting Capability

The ISL8016 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.

• Peak current limiting, Hiccup Mode Short Circuit Protection

and Over-Temperature Protection‘

Applications

The ISL8016 is offered in a space saving 20 Ld 3x4 QFN lead free

package with exposed pad lead frames for excellent thermal

performance. The complete converter occupies less than 0.15in

• DC/DC POL Modules

• µC/µP, FPGA and DSP Power

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

• Portable Instruments
