描述
The RTKA212832DR0000BU provides a simple platform to demonstrate the performance of RAA212832, a synchronous buck regulator with 2 LDO outputs. The evaluation board can support a wide input voltage range of 14V to 72V. The buck output is 12V capable of 500mA. The buck output is used as the input for the 5V 100mA and 3.3V 50mA LDO outputs. The buck output can also be set to 6V to further reduce power dissipation on the LDO rails.
