LY8010

® Rev. 1.6 2.5 W Mono Filterless Class D Audio power Amplifier (WCSP / DFN) GENERAL DESCRIPTION The LY8010 is a high efficiency, 2.5 W mono class D audio power amplifier. It is a low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplify design. The LY8010 is designed to meet of mobile phones and other portable electronic devices. The LY8010 is a single 5V supply, it is capable of driving 4Ω speaker load at a continuous average output of 2.5 W with 10% THD+N. Not external heat-sink is required. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the LY8010. Output pin short circuit ( short to output pin, short to ground and short to VDD ) protection prevent the device from damage during fault conditions. LY8010 FEATURES „ 2.5 W Into 4Ω from 5V power supply at THD = 10% (Typ). „ 2.5V~5.5V Power supply. „ Low shutdown Current. „ Low Quiescent Current. „ Minimum external components. „ No output filter required for inductive loads. „ Output Pin Short-Circuit Protection (Short to Output Pin, Short to GND, Short to VDD) „ Low noise during turn-on and turn-off transitions. „ Lead free and green package available.
