OB6228SP is a two-channel Class-D audio power amplifier. Wide supply voltage 8.5-15V. The output power can support 15.5W continuous output for each channel (15V supply 8Ω load) and the efficiency is up to 86%.
The advanced and unique dynamic drive control technology enables the OB6228SP to have perfect EMC performance, and the output does not need LC filtering.
The integrated output over-current protection, on-chip over-temperature protection, power supply over-voltage and under-voltage protection, input DC protection and other functions make the OB6228SP more safe and reliable in some abnormal situations.
The integrated power limiting function enables the OB6228SP to flexibly adapt to multiple loads under the same power supply situation.
The output over-current protection and over-temperature protection have a self-recovery function with real-time detection.
In the case of abnormal DC input, the DC input protection turns off the output until it is powered on again, protecting the speaker from damage.
OB6228SP is a TSSOP28 package, and the thermal pad on the bottom of the package effectively helps dissipate heat.
