ETA1133 Description
ETA1133 is highly efficient 2.5 MHz, 1.5A input current, step-up DC-to-DC converter. ETA1133 converts input voltages from 2.5 V to 5.25 V to a fixed output voltage of 5.4V. Unlike most step-up converter, it incorporates circuits that disconnect the input from output, during shutdown, short-circuit, output current overloading, or other events when output is higher than the input.
