IS31AP2036A中文资料Advanced K-charge pump to boost supply volt- age with a 92% efficiency and increased ampli- fier efficiency of 75%数据手册Lumissil规格书

描述 Description

The IS31AP2036A is a Class-K audio power amplifier with high efficiency and automatic gain control. It drives up to 2.0W (10% THD+N) into an 8Ω speaker from a 4.2V VCC supply.

The IS31AP2036A integrates advanced high efficiency charge pump and whole power amplifier efficiency can be up to 75%. The output power will be maintained in 0.8W, 1.0W and 1.2W.

The IS31AP2036A provides low cost, space saving solution for portable equipments which need audio output with higher power by boosting up supply voltage. Its external components just include a few capacitors and resistors (no inductor).

The IS31AP2036A use fully differential design to reduce RF noise. The IS31AP2036A integrates de-pop circuitry to reduce pop and click noise during power on/off or shutdown enable operation. The IS31AP2036A also integrates thermal and short circuit protection function.

IS31AP2036A is available in FCQFN-16 (2mm × 2mm) package. It operates from 3.0V to 5.0V over the temperature range of -40°C to +85°C.
