*3 : When a component with a resistance accuracy of ±1% is used
<Reference> When a component with a resistance accuracy of ±0.5% is used, VO3” is 8.67V ≤ 9.0V ≤ 9.33V.
*4 : When a component with a resistance accuracy of ±1% is used
The absolute accuracy of the internal resistance is ±15%.
*5 : Since the SW 5V and ACC 5V are output from VDD 5V through the SW, the voltage drops by an amount equivalent to the ON resistance of the SW.
*6: The entire specification has been defined based on the tests performed under the conditions where Tj and Ta (=25°C) are almost equal. There tests were
performed with pulse load to minimize the increase of junction temperature (Tj).

HZIP15J Heat sink attachment
Heat sinks are used to lower the semiconductor device junction temperature by leading the head generated by the device to
the outer environment and dissipating that heat.
a. Unless otherwise specified, for power ICs with tabs and power ICs with attached heat sinks, solder must not be
applied to the heat sink or tabs.
b.
Heat sink attachment
· Use flat-head screws to attach heat sinks.
· Use also washer to protect the package.
· Use tightening torques in the ranges 39-59Ncm(4-6kgcm) .
· If tapping screws are used, do not use screws with a diameter larger
than the holes in the semiconductor device itself.
· Do not make gap, dust, or other contaminants to get between the
semiconductor device and the tab or heat sink.
· Take care a position of via hole .
· Do not allow dirt, dust, or other contaminants to get between the
semiconductor device and the tab or heat sink.
· Verify that there are no press burrs or screw-hole burrs on the heat sink.
· Warping in heat sinks and printed circuit boards must be no more than
0.05 mm between screw holes, for either concave or convex warping.
· Twisting must be limited to under 0.05 mm.
· Heat sink and semiconductor device are mounted in parallel.
Take care of electric or compressed air drivers
· The speed of these torque wrenches should never exceed 700 rpm, and
should typically be about 400 rpm.

c.
Silicone grease
· Spread the silicone grease evenly when mounting heat sinks.
· Sanyo recommends YG-6260 (Momentive Performance Materials Japan LLC)
d.
Mount
· First mount the heat sink on the semiconductor device, and then mount that assembly on the printed circuit board.
· When attaching a heat sink after mounting a semiconductor device into the printed circuit board, when tightening
up a heat sink with the screw, the mechanical stress which is impossible to the semiconductor device and the pin
doesn't hang.
e.
When mounting the semiconductor device to the heat sink using jigs, etc.,
· Take care not to allow the device to ride onto the jig or positioning dowel.
· Design the jig so that no unreasonable mechanical stress is not applied to the semiconductor device.
f.
Heat sink screw holes
· Be sure that chamfering and shear drop of heat sinks must not be larger than the diameter of screw head used.
· When using nuts, do not make the heat sink hole diameters larger than the diameter of the head of the screws used.
A hole diameter about 15% larger than the diameter of the screw is desirable.
· When tap screws are used, be sure that the diameter of the holes in the heat sink are not too small. A diameter about
15% smaller than the diameter of the screw is desirable.
g.
There is a method to mount the semiconductor device to the heat sink by using a spring band. But this method is not
recommended because of possible displacement due to fluctuation of the spring force with time or vibration.
Caution for implementing LV5680P to a system board
The package of LV5680P is HZIP15J which has some metal exposures other than connection pins and heatsink as shown in the
diagram below. The electrical potentials of (2) and (3) are the same as those of pin 15 and pin 1, respectively. (2) (=pin 15) is the VCC
pin and (3) (=pin 1) is the ILM (regulator) output pin. When you implement the IC to the set board, make sure that the bolts and the
heatsink are out of touch from (2) and (3). If the metal exposures touch the bolts which has the same electrical potential with GND,
GND short occurs in ILM output and VCC. The exposures of (1) are connected to heatsink which has the same electrical potential with
substrate of the IC chip (GND). Therefore, (1) and GND electrical potential of the set board can connect each other.
