特性 Features

• Output: POUT = 13 W × 2ch (typ.) BTL

VCC = 12 V, RL = 4 Ω, THD = 10, f = 1 kHz

POUT = 7.5 W × 2ch (typ.) BTL

VCC = 12 V, RL = 8 Ω, THD = 10, f = 1 kHz

POUT = 19.5 W × 2ch (typ.) BTL

VCC = 15 V, RL = 4 Ω, THD = 10, f = 1 kHz

POUT = 21 W × 2ch (typ.) BTL

VCC = 20 V, RL = 8 Ω, THD = 10, f = 1 kHz

• High efficiency: When output is 10 W η = 88 (VCC = 15 V, RL = 8 Ω)

• 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 (4 Ω): VCC (opr) = 11 V to 18 V (Topr = 0°C to 75°C),

VCC (opr) = 11.4 V to 18 V (Topr = −20°C to 75°C)

• Operating supply voltage range (8 Ω): VCC (opr) = 11 V to 20 V (Topr = 0°C to 75°C),

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 TB2924AFG does not contain protection circuitry for shorts against VCC and ground. Extra cares, such as

incerting fuses, should be exercised when output pins serve as line output or adjacent pins are shorted together

on the board.
