LM27762EVM: ±1.8 ~ ±5.2V @ 250mA, 2.7 ~ 5.5V in

Summary

This user's guide describes the characteristics, operation, and use of the LM27762 evaluation module (EVM). This user's guide includes a schematic diagram and bill of materials (BOM).

The Texas Instruments LM27762EVM evaluation module helps designers evaluate the operation and performance of LM27762 integrated circuit (IC). More information about the LM27762 capabilities can be found in the datasheet.

The EVM contains one LM27762 low-noise regulated switched-capacitor voltage inverter and positive LDO. For more details and electrical characteristics of this device, see the LM27762 device data sheet.The LM27762 is a low-noise regulated switched-capacitor voltage inverter with both positive and negative LDOs. It delivers 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. The regulated output for the LM27762 is adjustable between ±1.8 V and ±5.2 V.
