DA9210 Multi-Phase 12 A DC-DC Buck Converter
General Description
DA9210 is a multi-phase synchronous step-down converter suitable for supplying the CPU power in
smartphones, tablets, UltrabooksTM, and other handheld applications, which require high currents to
run the processor core.
DA9210 is designed to operate with four phases, each phase using a small external 0.47 µH
inductor. The buck is capable of delivering up to 12 A continuous output current with an output
voltage of 0.3 V to 1.57 V. The input voltage range of 2.8 V to 5.5 V makes it suited for a wide variety
of low voltage systems, including all Li-Ion battery supplied applications. Two DA9210s can be used
in parallel to deliver an output current of up to 24 A.
The DA9210 point-of-load remote-sensing feature guarantees the highest accuracy while supporting
multiple PCB routing scenarios without loss of performance. The highly-integrated design removes
the need for external switching FETs or Schottky diodes.
A programmable soft start-up can be enabled, which limits the inrush current from the input node and
ensures a slope controlled activation of the rail.
The Dynamic Voltage Control (DVC) supports adaptive adjustment of the supply voltage dependent
on the processor load. This is done via direct register write through the communication interface (I2C
or SPI compatible), via the dedicated DVC control interface, or via a programmable input pin.
DA9210 integrates over-temperature and over-current protection for increased system reliability,
without the need for external sensing components. A Power Good and Over-Current Alarm output
informs the CPU of an out range voltage output and if the current exceeds a programmable limit,
thereby enabling the processor to reduce its consumption before the supply rail collapses.
