LM2731XEVAL [Texas Instruments]

The LM2731 and LM2733 are boost regulators with internal switch FETs. The LM2731 has a higher current internal switch FET with lower breakdown voltage, while the LM2733 has a higher voltage FET that handles less current. The LM2733 targets applications with higher output voltages, while the LM2731 is intended for applications requiring higher load currents at lower output voltages. The evaluation boards demonstrate operation with component selection guidelines for inductors, diodes, and output capacitors. Output voltage is adjustable using resistor networks R2 and R3, with feedforward compensation for stability.
