DA9121
Configurable, 10A Dual-Phase SubPMIC for high performance mobile processors and memory
10A, Dual Phase I2C Controlled SubPMIC
DA9121 is a SubPMIC suitable for supplying CPUs, GPUs, DDR memory rails in smartphones, tablets, RF modules and other handheld applications.
DA9121 operates as a single-channel dual-phase buck converter, each phase requiring a small external 0.10 μH inductor. It is capable of delivering up to 10A output current at a 0.3 V to 1.9 V output voltage range. The 2.5 V to 5.5 V input voltage range is suitable for a wide variety of low voltage systems, including, but not limited to, all Li-Ion battery supplied applications.
Features
2.5 V to 5.5 V input voltage
0.3 V to 1.9 V output voltage
4 MHz nominal switching frequency
±1 % accuracy (static)
±5 % accuracy (dynamic)
I2C-compatible interface (FM+)
Configurable GPIOs
Programmable soft-start
Voltage, current, and temperature supervision
-40 °C to +85 ºC ambient temperature range
Benefits
Input voltage range provides flexibility to run from single cell Li-Ion battery or standard 3.3V or 5V system rail
Differential voltage sensing provides tight regulation accuracy requirements of CPU cores in mobile SoCs
4MHz switching frequency reduces footprint & height of output inductor and minimizes output capacitance, lowering BOM cost
Triggered through either an I2C or GPIO interface, output dynamic voltage control can be used to optimize system power consumption
