Features
• The STK4102II series (STK4102II) and STK4101V
series (high-grade type) are pin-compatible in the output range of 6W to 50W. Once the PCB pattern is
designed, you can easily satisfy the requirements for

new sets simply be changing the IC.
• Small-sized package whose pin assignment is the same
as that of the STK4101II series
• Built-in muting circuit to cut off various kinds of pop
noise
• Greatly reduced heat sink due to substrate temperature
125 ° C guaranteed
• Excellent cost performance

Notes. For power supply at the time of test, use a constant-voltage power
supply unless otherwise specified.
For measurement of the available time for load short-circuit and output noise voltage, use the specified transformer power supply shown
right.
The output noise voltage is represented by the peak value on rms
scale (VTVM) of average value indicating type. For AC power supply,
use an AC stabilized power supply (50Hz) to eliminate the effect of
flicker noise in AC primary line.
