Ordering number : EN*A1621 Thick-Film Hybrid IC STK416-090-E Overview 3-Channel Power Switching Audio Power IC, 80W+80W+80W The STK416-090-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 • Pin-to-pin compatible outputs ranging from 80W to 180W. • Can be used to replace the STK415-100 series (2-channel models) and the class-AB series (2, 3-channel models) due to its pin compatibility. • Pure complementary construction by new Darlington power transistors • Output load impedance: RL = 8Ω to 4Ω supported • Using insulated metal substrate that features superlative heat dissipation characteristics that are among the highest in the industry.

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: Please connect –Pre VCC pin (#5 pin) with the stable minimum voltage and connect so that current does not flow in by reverse bias. *7: Use the standby pin (pin 17) so that the applied voltage never exceeds the maximum rating. The power amplifier is turned on by applying +2.5V to +5.5V to the standby pin (pin 17). Continued on next page.
