Multiphase 15A and 5A Output Current

A team of engineers is ready to answer your questions

Flexible, Scalable, Reliable Automotive Grade power management IC (PMIC) solution 

The DA9215-A is a flexible, scalable dual output sub PMIC capable of meeting the high power requirements of a wide range of multicore SoCs, GPUs, and FPGAs.  The device includes two high-current buck converters providing up to twenty amps per buck. Suitable for infotainment, telematics, and ADAS applications, the high current bucks feature a multiphase topology providing outstanding load transient response. All bucks use integrated power switches, removing the need for external FETs.  Together with the high device switching frequency that allows the use of low-profile inductors, they enable the lowest cost, smallest form factor system solution possible.   High efficiency is achieved over a wide load range by automatically selecting Pulse Frequency Modulation (PFM) or Pulse Width Modulation (PWM) modes. The input voltage range of 2.8 to 5.5 V makes it suitable for standard 5 V supply or USB power supplies. This solution is also available in Automotive AEC-Q100 Grade 2.
