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.
Features
Output: POUT = 13 W × 2ch (typ.) BTL
VCC = 12 V, RL = 4 , THD = 10%, f = 1 kHz
POUT = 7.5 W × 2ch (typ.) BTL
VCC = 12 V, RL = 8 , THD = 10%, f = 1 kHz
POUT = 19.5 W × 2ch (typ.) BTL
VCC = 15 V, RL = 4 , THD = 10%, f = 1 kHz
POUT = 21 W × 2ch (typ.) BTL
VCC = 20 V, RL = 8 , THD = 10%, f = 1 kHz
High efficiency: When output is 10 W
η = 88% (VCC = 15 V, RL = 8 )
Distortion: 0.1% (1 W output, f = 1 kHz)
Gain: 34dB (typ.)
Small flat package: HSOP36-P-450-0.65
Muting/standby features
Thermal AGC features
Master and slave oscillation frequencies
Oscillation frequency: fsw = 200 kHz (typ.)
Operating supply voltage range: VCC (opr) = 11 V to 18V (Topr = 0°C to 75°C),
(4
)
VCC (opr) = 11.4 V to 18 V (Topr = 20°C to 75°C)
Operating supply voltage range: VCC (opr) = 11 V to 20V (Topr = 0°C to 75°C),
(8
)
VCC (opr) = 11.4 V to 20 V (Topr = 20°C to 75°C)
Protective circuits: thermal shutdown, short-circuit protection (load)
These protection functions are intended to avoid some output short circuits or other abnormal conditions
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 (VCC = 15 V, RL = 8 , THD = 10%, f = 1 kHz) with a
sine-wave input.
This product are sensitive to electrostatic discharge. When handling this product, protect the environment to
avoid electrostatic discharge.(MM:±200V OK,HBM:±1500V OK)
Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product
or equipment.
