General Description

XL2050A is a mono Class AB audio power

amplifier optimized for high voltage, high

power and high efficiency. XL2050A has low

quiescent current and minimizing system

power consumption. XL2050A has excellent

audio performance and achieved extremely

low distortion levels even at 35W power

levels.

The XL2050A built-in over power protection,

current limit protection, output overvoltage

protection, output short protection, and

thermal shutdown protection， which greatly

improves the reliability and stability of the chip.

The XL2050A achieves 20W@THD=0.015%

of output power at an input voltage of ±25V

and a load impedance of 4Ω or 8Ω, and

35W@THD=1% at an input voltage of ±30V

and a load impedance of 4Ω or 8Ω. The

highly integrated solution can reduce the

printed circuit board space while minimizing

external components.
