[CTRL1/2/3 input]
CTRL1 accepts three input values (L/M/H).,
CTRL2 accepts four input values(L/M1/M2/H)
and CTRL3 accepts two values(L/H).
CTRL1/2/3 have a pull-down resistance, and
this resistance value is 400kΩ.
Logic table is shown on page7.
[VCC/VCC1]
VCC1 voltage must be higher than VCC-0.7V,
because internal diode between VCC and
VCC1 becomes positively biased. This internal
diode cannot be used to supply current from
VCC to VCC1 because this is used only for
ESD protection purpose.
[Protection]
Thermal Shutdown
To protect the device from overheating a
thermal shutdown circuit is included. If the
junction temperature reaches approximately
175 ℃ (typ), all outputs are turned off
regardless of CTRL state. Outputs remain
disabled until the junction temperature drops
below 145℃(typ)(automatic restoration).
The thermal shutdown circuit does not
guarantee the protection of the final product
because it operates out of maximum rating
(exceeding Tjmax=150℃).
Current Limiting
When the each output becomes in over load
condition, the device limits the output current.
All outputs are also protected against short
circuit by fold back current limiter.
Overvoltage
The device is protected against load dump.
When VCC voltage exceeds 21V, the device
detects over voltage condition and turns all the
outputs off except VDD to protect the device. If
VCC voltage gets below 21V, outputs are
automatically restored.
TEST Procedure
Line regulation
Line regulation is defined as the maximum
change in output voltage as the input voltage
is varied through the specified range. It is
measured by changing the input voltage and
measuring the minimum/maximum voltage of
the output. Line regulation is defined as the
difference between maximum and minimum
voltage.
Load regulation
Load regulation is defined as the maximum
change in output voltage as the load current is
varied through the specified range. It is
measured by changing the load current and
measuring the minimum/maximum voltage of
the output. Load regulation is defined as the
difference between maximum and minimum
voltage.
Dropout voltage
Dropout voltage is defined as the minimum
input-to-output differential voltage at the
specified load current required by the regulator
to keep the output voltage in regulation. It is
measured by reducing input voltage until the
output voltage drops below the nominal value.
Ripple rejection
Ripple rejection is defined as the ratio of input
ripple amplitude versus that of output.
