DA14531 Hardware Design Examples

Description

For DA14531, Dialog provides Design Examples files to help customers develop their PCB. These examples show a minimum size layout using the minimum number of external components on a 2-layer PCB. For details on layout guidelines and component selection, see the Application Note AN-B-075 available on the Dialog website.

The following Design Examples files are available: - Boost configuration: better power efficiency at low supply voltage - Buck configuration: better power efficiency at high supply voltage - Bypass mode: lowest cost because no inductor is used. DCDC converter is disabled, resulting in a lower power efficiency

The provided Design Examples files contain the following components:

  • DA14531 chip in 24 pin FCGQFN package

  • DA14531 chip in 17 pin WLCSP package

  • The AT25DF011 Flash

  • 32 MHz XTAL

  • Inductor (Buck and Boost only)

  • De-coupling/matching components

  • PCB Antenna

A small strip antenna design is connected to the chip antenna port. The antenna efficiency and radiation patterns are described in the DA14531 Module Datasheet.

For different antenna designs, see the following documents:

The Design Examples (FCGQFN and WLCSP) are delivered as a .zip file and contain the following items:
