DA9121-B0V72 is a high-performance, 10A, dual-phase DC-DC converter. It is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails in single in-line pin package (SIPP) modules, smartphones, tablets, and other handheld applications. With remote sensing, the DA9121 guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance. The pass device is 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 rail activation. Application includes SIPP modules (SoC, DRAM), smartphones, tablet PCs, infotainment, Ultrabooks™, Wi-Fi Modules, and game consoles.
- Input voltage range from 2.5 to 5.5V (VIN=VSYS, TJ=-40°C to +125°C)
- Output voltage range from 0.3V to 1.9V (TJ=-40°C to +125°C)
- Switching frequency, posttrim is 4MHz typ (TJ=-40°C to +125°C)
- Output voltage accuracy, including static line and load regulation is -1% min (TJ=-40°C to +125°C)
- I²C-compatible interface (FM+), programmable GPIOs, programmable soft-start
- Voltage, current, and temperature supervision
- Quiescent current in PFM is 164µA typ (VIN=3.7V, no load, no switching)
- Turn-on time is 20µs max (CHx-EN=high, TJ=-40°C to +125°C)
- Line transient response is 15mV typ (VIN=3V to 3.6V, IOUT=0.5 IMAX, dt=10µs)
- 24 WLCSP package, ambient temperature range from -40 to 85°C
