The EV7770-F-01B is the bridge-tied load (BTL) configuration evaluation board for the MP7770, which can deliver 90W into 8Ω speakers under a 36V input voltage (V_DD). This fully integrated audio amplifier dramatically reduces solution size by integrating 100mΩ power MOSFETs, start-up/shutdown pop elimination, and short-circuit protection (SCP) circuits.

MPS’s Class-D audio amplifiers exhibit the high fidelity of a Class-A/B amplifier at higher efficiencies. The circuit is based on MPS’s proprietary variable-frequency topology, which delivers excellent linearity and fast response time, operating from a single power supply.

The MP7770 is available in a TSSOP-28EP package.
