3W Class-D Audio Power Amplifier

with Auto-Recovering Short-Circuit Protection

GENERAL DESCRIPTION

FEATURES



Filterless Class-D operation

The ft2010 is a high efficiency, filterless, Class-D

audio amplifier with auto-recovering short-circuit

protection. It operates from 2.7V to 5.5V supply.

When powered with 5V supply voltage, the ft2010

is capable of delivering 3W into a 4Ω load or 1.8W

into an 8Ω load, with 10% THD+N.

High efficiency up to 90%

Maximum output power at 5V supply

3.0W (4Ω load, 10% THD+N)

1.8W (8Ω load, 10% THD+N)



Maximum output power at 3.6V supply

As a Class-D audio amplifier, the ft2010 features

90% efficiency and 75dB PSRR at 217Hz which

make the device ideal for battery-powered

high-quality audio applications.

1.5W (4Ω load, 10% THD+N)

0.9W (8Ω load, 10% THD+N)

Low THD+N: 0.05%

(VDD=3.6V, f=1kHz, RL=8Ω, PO=0.5W)

One of the key benefits of the ft2010 over typical

Class-D audio power amplifiers is it generates

much less EMI emissions, thus greatly simplifying

the system design for portable applications. Also

included is the over-current and short-circuit

protection with auto-recovery, which ensures the

device be operated safely and reliably without the

need for system interaction.



Low quiescent current: 2mA @ VDD=3.6V

Low shutdown current < 0.1µA

High PSRR: 75dB @ 217Hz

No bypass capacitor required for the

common-mode bias



Under-voltage lockout

Auto-recovering over-current and

short-circuit protection
