25A steady state current, and has a 250kHz channel
switching frequency. This circuit also switches to single
channel operation for Deep and Deeper Sleep modes of
operation. For thermal compensation, PTC resistors are
used as sense resistors. The output capacitance is less
than 3mΩ of ESR, and are (4) 220µF, 4V Sp-Cap parts in
parallel with (35) high frequency, 10µF ceramic capacitors.
