Renesas DA9220-EVAL1

Overview

DA9220-EVAL1 from Renesas Electronics is an evaluation board designed specifically for the DA9220 two-channel, one-phase buck converter PMIC. It supports input voltage range of 2.5 V to 5.5 V, delivers configurable output voltages from 0.3 V to 1.57 V per channel, and enables full register-level configuration and real-time monitoring via I²C using the SmartCanvas GUI software.

For engineers reviewing the DA9220-EVAL1 datasheet, DA9220-EVAL1 pinout, DA9220-EVAL1 application, or DA9220-EVAL1 equivalent, this board provides hands-on validation of power sequencing, soft-start behavior, GPIO control, and fault-event logging in Li-ion battery-powered embedded systems requiring dual-rail low-voltage regulation.

Technical Context

The DA9220-EVAL1 implements the DA9220 PMIC in a fully assembled, test-ready layout with accessible test points, configurable jumpers (J7, J10–J14, J16), and on-board USB-I²C interface compatibility. It exposes all critical signals-including EN, GPIO0–GPIO2, SDA/SCL, and VSYS/AVDD/VDDIO-for hardware validation and firmware integration testing.

Hardware design includes dedicated links for pull-up/pull-down configuration of control pins, selectable I²C bus termination, and direct connection support for the Dialog/RENESAS USB-I²C module (162-09). The board operates with no external components required beyond the host PC and USB cable.

FAQ

What is the primary function of the DA9220-EVAL1?

The DA9220-EVAL1 is a dedicated evaluation board for the DA9220 two-channel buck PMIC. It provides a ready-to-use hardware platform to configure, monitor, and validate the DA9220's dual-output regulation, power sequencing, GPIO control, and fault reporting capabilities using the SmartCanvas GUI over I²C. DA9220-EVAL1 does not contain active ICs beyond the target DA9220 device and supporting passive components.

Which PMIC does the DA9220-EVAL1 support?

The DA9220-EVAL1 is designed exclusively for the DA9220 PMIC - a two-channel, one-phase synchronous buck converter with integrated power FETs, programmable soft-start, and non-volatile register defaults. It is not compatible with the DA9217, DA9121, or DA9122, which require the separate DA9217-EVAL1 (368-01) board.

How is communication established between the PC and DA9220-EVAL1?

Communication uses a USB-I²C interface module (162-09) connected between the PC and DA9220-EVAL1's J17 header. The included SmartCanvas GUI software communicates via standard I²C protocol at default 8-bit address 0xD0. The USB-IO driver must be installed first, and Windows Device Manager confirms successful enumeration under "Dialog Semiconductor" devices.

What jumper configurations are available on the DA9220-EVAL1?

The DA9220-EVAL1 includes configurable jumpers J10–J14 and J16 for GPIO0–GPIO2, IC_EN, SDA/SCL, and AVDD/VSYS routing. For example, J10 selects whether GPIO0 is pulled to VDDIO or GND; J13 configures I²C bus pull-up voltage source; and J16 connects VDDIO to the USB-I²C module's 3.3 V output. All configurations are documented in Table 1 of UM-PM-041.

Does the DA9220-EVAL1 require external power supplies?

No - the DA9220-EVAL1 derives all operating power from the USB-I²C module's 3.3 V output (via J16) and the target DA9220's VSYS input (2.5–5.5 V), which can be supplied by an external bench supply or battery emulator. No auxiliary power rails or AC adapters are needed for basic functional evaluation.
