Topdiode’s multilevel class D audio amplifier circuit technology – the world’s first of its kind – has made it possible to improve power consumption while reducing electromagnetic interference and out-of-band noise. Manufacturing costs can also be reduced by eliminating or minimizing the use of filters, helping to save design space.
Compare with traditional class D amplifier is a switching amplifier, usually consisting of two power MOSFETs with pulse-width-modulation (PWM) signal. An LC filter is needed for output levels >20 W which increases both size and costs. Topdiode revolutionary multilevel class D amplifier ICs, Topdiode leads in power efficiency and power density. Cooler, smaller, and lighter class D audio amplifiers for great sounding products.
Topdiode Class D audio amplifier lC benefits
Experience sound like never before. Topdiode’s audio amplifier lC products are engineered to deliver unmatched clarity, guided by three core principles of audio amplifier performance.
Topdiode Class D Audio Amplifier ICs offer the following advantages:
- Power Efficiency: Maximize sound output in speakers, not heat to the surroundings.
- Integration: Compact and lightweight designs are the future; bulky and heavy are things of the past.
- Quality: Built to be robust and adaptable, not fragile and demanding.
Topdiode Class D amplifier IC applications
Topdiode Class-D Audio ICs are multilevel Class-D audio amplifier solutions featuring an embedded digital power management scheme. These ICs consume significantly less input power (~0.25W) and offer high power output in a small form without compromising the produced sound’s quality. A power management algorithm dynamically adjusts the switching frequency and modulation scheme to optimize power loss and EMI across the output power range. Flexible power mode profiles allow users to utilize the multilevel switching technique for very low power loss or high audio performance.
Portable/battery powered audio applications
