Figure 17. Typical Application of DA9215

Figure 17 shows a typical use case of DA9215 for the simultaneous supply of a CPU and a GPU rail. The IC is

always enabled because IC_EN is shorted to the battery voltage. The CORE application processor enables and

disables the CPU/GPU and the DDR individually via dedicated ports on DA9215.

Table 11 shows how the phases of the device are used for different device configurations. It should be noted in

particular that the third phase of DA9215 BuckA is phase B2. Phase B1 is used for the single phase BuckB.

5.1

DC_DC Buck Converter

DA9213 is a four-phase 20 A high efficiency synchronous step-down DVC regulator, operating at a high

frequency of typically 3 MHz. It supplies an output voltage of typically 1.0 V for a CPU rail, configurable in the

range 0.3 V to 1.57 V, with high accuracy in steps of 10 mV.

DA9214 contains two buck converters, Buck A and Buck B, each capable of delivering 10 A.
