DESCRIPTION
The MP1543 is a highly efficient, synchronous, fixed frequency, current-mode
step-up converter with output to input disconnect, inrush current limiting and
internal soft-start. It includes an error amplifier, ramp generator,
comparator, N-Channel switch and P-Channel synchronous rectified switch (which
greatly improves efficiency). The output disconnect feature allows the output
to be completely isolated from the input in shutdown mode.
The 500KHz switching frequency allows for smaller external components
producing a compact solution for a wide range of load currents. The internal
compensation and soft-start minimizes the external component count and limits
the inrush current during startup. The MP1543 regulates the output voltage up
to 6V and provides up to 400mA from a 2-cell AA with a 3.3V output.
