Description
The A4450 is a power management IC that can implementeither a buck or buck-boost regulator to efficiently convertautomotive battery voltages into a tightly regulated voltage.It is Allegro / A4450 / 8V-500kHz/1A / Buck Boost
Features
Automotive AEC-Q100 qualified
- Wide operating range of 3 to 36 VIN, 40 VIN maximum,covers automotive stop/start, cold crank, double battery,and load dump
- Regulated output can range from 3 to 8 V at up to 1 A DC
- Adjustable PWM switching frequency:250 kHz to 2.2 MHz
- PWM frequency can be synchronized to external clock:250 kHz to 2.4 MHz
- Frequency dithering helps reduce EMI/EMC
- Undervoltage protection
- Pin-to-pin and pin-to-ground tolerant at every pin
- Thermal shutdown protection
- Operating junction temperature range −40°C to 150°C
Typical applications
