regulation for the Intel IMVP-IV™ and IMVP-IV+™
application. The circuit uses 2 channels for delivering up to
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.
