1.2A Integrated FETs, High Efficiency
Synchronous Buck Regulator
ISL8011 is an integrated FET, 1.2A synchronous buck
regulator for general purpose point-of load applications . It is
optimized for generating low output voltages down to 0.8V.
The supply voltage range is from 2.7V to 5.5V allowing the
use from common 3.3V or 5V supply rails and Lithium ion
battery inputs. It has guaranteed minimum output current of
1.2A. 1.5MHz pulse-width modulation (PWM) switching
frequency allowing the use of small external components.
The ISL8011 includes 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 voltage at 1.2A.
The ISL8011 offers a 200ms Power-On-Reset (POR) timer
at power-up. When shutdown, the ISL8011 discharges the
output capacitor. Other features include internal digital
soft-start, enable for power sequence, overcurrent
protection, and thermal shutdown.
The ISL8011 is offered in a 10 Ld 3mmx3mm DFN package
with 1mm maximum height. The complete converter
occupies less than 1cm 2 area.
