TB2924FG  
TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic  
TB2924FG  
Class D, 20 W × 2-channel (BTL) Low-Frequency Power Amplifier IC  
The TB2924FG is an audio output IC that employs the highly  
efficient class D method, developed for TV and home audio  
applications.  
The TB2924FG eliminates the need for heatsink(Note), thus  
allowing the design of an end product with a small footprint. It  
also incorporates a range of features, such as standby and muting,  
as well as different protective circuits.

temporarily.  
These protect functions do not warrant to prevent the IC from being damaged.  
In case of the product would be operated with exceeded guaranteed operating ranges, these protection features  
may not operate and some output short circuits may result in the IC being damaged.  
The TB2924FG does not contain protection circuitry for shorts against VCC and ground. Extra care should be  
exercised when output pins serve as line output or adjacent pins are shorted together on the board.  
Note: Generally, the average power of the audio signal constitutes only one-fifth to one-tenth of the maximum output  
power, and in practice, will not exceed the permissible loss. However, care should be exercised so that it will  
not be really exceeded, considering the board’s thermal resistance, ambient temperature, average output  
power and so forth. Toshiba has verified that the TB2924FG works properly without a heatsink on the Toshiba  
PC board for up to 10-watt by 2-channel output typical (V
