The ISL85001 is a high-performance, simple output controller
that provides a single, high frequency power solution for a
variety of point-of-load applications. The ISL85001 integrates a
1A standard buck PWM controller and switching MOSFET. Features The PWM controller in the ISL85001 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 for up to 1A 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 ISL85001
power-good signal output indicates loss of regulation on the
PWM output. Integrated boot diode ISL85001 is available in a small 4mmx3mm Dual Flat No-Lead
(DFN) package. Related Literature For a full list of related documents, visit our website
