DA9213-A and DA9214-A

Auto Grade Multi-Phase 5A/Phase Buck Converter

General Description

DA9213-A and DA9214-A are PMICs optimized for the supply of CPUs, GPUs, and DDR memory

rails in automotive in-vehicle infotainment systems, Advanced Driver Assistance Systems (ADAS),

navigation and telematics applications. The fast transient response (10 A/µs) and load regulation are

optimized for the latest generation of multi core application processors.

DA9213-A operates as a single four-phase buck converter delivering up to 20 A output current.

DA9214-A integrates two dual-phase buck converters, capable of delivering 2x10 A output current.

Each buck regulates a programmable output voltage in the range 0.3 - 1.57 V. With an external

resistor divider the output voltage can be set to any voltage between 1.57 V and 4.3 V. The input

voltage range of 2.8 – 5.5 V makes it suited for a wide variety of low voltage systems, including all

Li-Ion battery powered applications.

To guarantee the highest accuracy and to support multiple PCB routing scenarios without loss of

performance, a remote sensing capability is implemented in both the DA9213-A and DA9214-A.

The power devices are fully integrated, so no external FETs or Schottky diodes are needed.

A programmable soft start-up can be enabled, which limits the inrush current from the input node and

secures a slope controlled activation of the rail.

The Dynamic Voltage Control (DVC) supports adaptive adjustment of the supply voltage depending

on the processor load, either via direct register writes through the communication interface (I²C or

SPI compatible) or via an input pin.

DA9213-A and DA9214-A feature integrated over-temperature and over-current protection for

increased system reliability without the need for external sensing components. The safety feature set

is completed by a VDDIO under voltage lockout.

The configurable I²C address selection via GPI allows multiple instances of DA9213-A and DA9214-

A to be placed in an application sharing the same communication interface with different addresses.
