2.2.2
VBAT
The DA16200 can operate one source for an I/O interface and internal power source (LDO and DC-
DC converter), so it is important to reduce the noise component on this power line. All the input de-
coupling capacitors should be located nearby the DA61200 IC and the thickness of power traces
should be higher than 0.3 mm.
The operating voltage level of VDD is from 2.1 V to 3.6 V. This allows the use of two alkaline
batteries.
2.2.3
Internal DC-DC (DCDC_LX and DCDC_FB)
The DA16200 contains one DC-DC converter for the analog and digital parts. This DC-DC converter
needs to connect a series 4.7 µH power inductor for high-power efficiency and a shunt 10 µF
capacitor to reduce switching noise, so the inductor and capacitor should be located as close as
possible for stable power supply. And 1 µF bypass capacitors are required for the power supply.
2.2.4
VDD_DA and VDD_PA
The DA16200 supports low Tx power mode for special application which doesn't need high Tx output
power. Only fcCSP type can support both low and normal Tx power mode and QFN package
supports normal Tx power mode only.
The difference between low and normal Tx power mode is the connection of VDD_PA and VDD_DA.
Those VDDs are connected to VBAT in normal Tx power mode and connected to DCDC output in
