MPS MP173GJ-Z

Неизолированный5,5 В ~ 5,7 В4 W

Overview

The MP1720DH-216-LF-Z 1720 is a high efficiency Class-D audio amplifier. It utilizes a full bridge output structure capable of delivering 2.7W into 4Ω speaker. This device exhibits the high fidelity of a class AB amplifier with an efficiency of 90% which dramatically reduces solution size by integrating the following:l  250mΩ power MOSFETs (VIN =3.3V)l  Startup / Shutdown pop eliminationl  Short circuit /Thermal overload ProtectionThe MP1720DH-216-LF-Z 1720 features a pin-selectable 1MHz or 1.3MHz frequency control or can be synchronized to an external clock source. The flexible switching frequency and internal EMI-reduction scheme eliminates the need for an   output LC filter and passes emission standards without filter & with considerable cable.The MP1720DH-216-LF-Z 1720 has five fixed gain options. MP1720-3: 3dB; MP1720-6: 6dB; MP1720-9: 9dB; MP1720-12: 12dB; MP1720-216: 21.6dB.The MP1720DH-216-LF-Z 1720 is available in 10-pin MSOP-EP and 10-pin QFN packages.
