Texas Instruments  LM27762EVM

The LM27762 evaluation module (EVM) helps designers evaluate the operation and performance of this device. The   LM27762EVM uses the LM27762 to provide very low-noise adjustable positive and negative outputs for an input voltage range of 2.7 V to 5.5 V. Five low-cost capacitors are used in this circuit to provide up to 250 mA of output current. More information about output voltage and current ratings of the LM27762EVM can be found in the LM27762 data sheet. Power-supply connection, connection for the load, and test points for each signal can be found on the evaluation board. Positive and negative output can be enabled individually by using onboard connectors.
