Typical Application - 2 Phase Converter
Using ISL6217A PWM Controller - 38 Lead
TSSOP
Figure 14 shows the ISL6217A, Synchronous Buck
Converter circuit used to provide the CORE voltage
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
3m of ESR, and are (4) 220µF, 4V Sp-Cap parts in parallel
with (35) high frequency, 10µF ceramic capacitors.

JEDEC MO-153-BD-1, Issue F.
2. Dimensioning and tolerancing per ANSI Y14.5M-1982.
3. Dimension “D” does not include mold flash, protrusions or gate burrs.
Mold flash, protrusion and gate burrs shall not exceed 0.15mm
(0.006 inch) per side.
4. Dimension “E1” does not include interlead flash or protrusions. Inter-
lead flash and protrusions shall not exceed 0.15mm (0.006 inch) per
side.
5. The chamfer on the body is optional. If it is not present, a visual index
feature must be located within the crosshatched area.
6. “L” is the length of terminal for soldering to a substrate.
7. “N” is the number of terminal positions.
8. Terminal numbers are shown for reference only.
9. Dimension “b” does not include dambar protrusion. Allowable dambar
protrusion shall be 0.08mm (0.003 inch) total in excess of “b” dimen-
sion at maximum material condition. Minimum space between protru-
sion and adjacent lead is 0.07mm (0.0027 inch).
10. Controlling dimension: MILLIMETER. Converted inch dimensions
are not necessarily exact. (Angles in degrees)
