Data Sheet
December 10, 2007
FN6611.0
2A Standard Buck PWM Regulator
The ISL8500 is a high-performance, simple output controller
that provides a single, high frequency power solution for a
variety of point-of-load applications. The ISL8500 integrates
a 2A standard buck PWM controller and switching MOSFET.
The PWM controller in the ISL8500 drives an internal
switching N-Channel power MOSFET and requires an
external Schottky diode to generate an output voltage from
0.6V to 19V. The integrated power switch is optimized for
excellent thermal performance up to 2A of output current.
The standard buck input voltage range supports a fixed 5V
or variable 5.5V to 25V range. The PWM regulator switches
at a fixed frequency of 500kHz and utilizes simple voltage
mode control with input voltage feed forward to provide
flexibility in component selection and minimize solution size.
Protection features include overcurrent, undervoltage and
thermal overload protection integrated into the IC. The
ISL8500 power good signal output indicates loss of
regulation on the PWM output.
ISL8500 is available in a small 4mmx3mm Dual Flat No-Lead
(DFN) package.
