Overview

A8660 Wide Input Voltage, Adjustable Output, Synchronous Buck Controller with PWM Frequency Dithering, Synchronization, and NPOR FEATURES AND BENEFITS • Automotive AEC-Q100 qualified • Wide operating voltage range: 3.
0 to 45 V • Adjustable output voltage • PWM frequency dithering reduces EMI/EMC signature and minimizes input filtering • Programmable base frequency (fOSC): 200 kHz to 2.
2 MHz • For low frequency, high current designs (<520 kHz), applying a clock to SYNCIN will synchronize the PWM frequency to avoid AM band harmonic interference • Soft recovery from dropout avoids overshoot of VOUT • External compensation provides flexibility to tune the system for maximum stability or optimu...
