A8660 Description
Designed to satisfy the power supply requirements of automotive, industrial, and consumer applications, the A8660 includes all the control and protection circuitry to produce a robust PWM controller delivering high current. The A8660 includes PWM frequency dithering, which has been shown to reduce EMI/EMC.
A8660 Key Features
- Automotive AEC-Q100 qualified
- Wide operating voltage range: 3.0 to 45 V
- Adjustable output voltage
- PWM frequency dithering reduces EMI/EMC signature
- Programmable base frequency (fOSC): 200 kHz to 2.2 MHz
- For low frequency, high current designs (<520 kHz)
- Soft recovery from dropout avoids overshoot of VOUT
- External pensation provides flexibility to tune the system for maximum stability or optimum transient response
- Adjustable soft-start time controls inrush current to acmodate a wide range of output capacitances
- Pre-bias startup allows quick, monotonic restart and avoids reset
