QCIOT-COMPMPOCZ
The QCIOT-COMPMPOCZ power board enables
quick prototyping of both the DA9313, a 5.5V to 10.5V
10A inductor-less power converter with power
efficiency up to 98%, and the ISL80103, a low voltage
6V, high-current 3A single-output LDO in a custom
system design. The ISL28025, a precision digital
power monitor, measures and controls the regulator
output of the ISL80103 with margining.
The board provides a standard Pmod™ Type 6A
2
(extended I
C) connection for the on-board sensor to
plug into any required MCU evaluation kit with a
matching connector. The QCIOT-COMPMPOCZ
features Pmod connectors on both sides of the board
to allow additional Type 6/6A boards to connect in a
daisy-chained solution with multiple devices on the
same MCU Pmod connector.
The software support that is included with the
2
Renesas IDE
(e
studio) provides code generation to
connect the device and the MCU so that the
development time is significantly reduced. With its
standard connector and software support, the
QCIOT-COMPMPOCZ is ideal for the Renesas
Quick-Connect IoT to rapidly create an IoT system.

QCIOT-COMPMPOCZ Evaluation Board Manual 4.3.2 Set Output DAC Voltage The set_reg_vol_to(USER_VOLTAGE) API sets the output voltage. The dropout voltage of the LDO ISL80103 is significantly less than 120mV at a maximum current of 3A. Ensure the difference between the Input voltage and the required output voltage is minimal so that the LDO is effective. - Page 19 Renesas' products are provided only subject to Renesas' Terms and Conditions of Sale or other applicable terms agreed to in writing.
