A8660
A8660 is Synchronous Buck Controller manufactured by Allegro MicroSystems.
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 pensation provides flexibility to tune the system for maximum stability or...
