Renesas Electronics RAA210030 Demonstration Board (RTKA210030DR0000BU)

Renesas Electronics RAA210030 Demonstration Board (RTKA210030DR0000BU) provides the peripheral circuitry to evaluate the feature set of the RAA210030 synchronous step-down non-isolated complete power supply module. This demo board is based on a peak current mode PWM control scheme that provides a fast transient response and excellent loop stability. The RTKA210030DR0000BU demo board offers adjustable output voltages down to 0.6V, up to 95% efficiency, and better than ±1.5% accuracy over line, load, and temperature. This board includes several connectors that simplify the validation of the RAA210030 power module. The RAA210130 demo board features UVLO, overcurrent, negative overcurrent, overvoltage, and over-temperature protections.

Features

  • Wide input voltage range from 2.7V to 5.5V
