Renesas ISL85001IRZ

降压降压4.5V25V1A

Overview

The ISL85001IRZ is a high-performance, simple output controller that provides a single, high frequency power solution for a variety of point-of-load applications. The ISL85001IRZ integrates a 2A standard buck PWM controller and switching MOSFET. The PWM controller in the ISL85001IRZ 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 ISL85001IRZ power good signal output indicates loss of regulation on the PWM output. ISL85001IRZ is available in a small 4mmx3mm Dual Flat No-Lead (DFN) package.
