Thick-Film Hybrid IC
STK412-150C-E Two-Channel Power Switching System
Audio Power IC, 150W+150W
Overview
The STK412-150C-E is a class H audio power amplifier hybrid IC that features a built-in power supply switching circuit.
This IC provides high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the
power devices according to the detected level of the input audio signal.
Applications
Audio power amplifiers.
Features
High output power by using power MOSFETs.
Output load impedance: RL = 8Ω to 6Ω supported
Using insulated metal substrate that features superlative heat dissipation characteristics that are among the highest in the
industry.

[Remarks]
*1: Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out.
*2: The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz)
power supply should be used to minimize the influence of AC primary side flicker noise on the reading.
*3: Use the designated transformer power supply circuit shown in the figure below for the measurements of allowable
load shorted time and output noise voltage.
*4: Design circuits so that (|VH|-|VL|) is always less than 40V when switching the power supply with the load
connected.
*5: Set up the VL power supply with an offset voltage at power supply switching (VL-VO) of about 8V as an initial
target.
*6: Weight of independent IC: 38.6g
