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. Itincludes control, diagnostics, and protection functions
Features
Automotive AEC-Q100 qualifiedWide operating range of 3 to 36 VIN, 40 VIN maximum, covers automotive stop/start, cold crank, double battery, and load dumpRegulated output can range from 3 to 8 V at up to 1 A DCAdjustable PWM switching frequency: 250 kHz to 2.2 MHzPWM frequency can be synchronized to external clock: 250 kHz to 2.4 MHzFrequency dithering helps reduce EMI/EMCUndervoltage protectionPin-to-pin and pin-to-ground tolerant at every pinThermal shutdown protectionOperating junction temperature range −40°C to 150°C
Typical applications
- Instrument Clusters
- Infotainment
- Control Modules
