Class-D Speaker Amplifier for Digital Input - BD5451EFV

BD5451EFV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-powerconsumption, delivers an output power of 15W+15W. This IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD)process technology that eliminates turn-on resistance in the output power stage and internal loss due to line resistances upto an ultimate level. With this technology, the IC can achieve high efficiency of 90% (15W+15W output with 8O load). Inaddition, the IC is packaged in a compact reverse heat radiation type power package to achieve low power consumptionand low heat generation and eliminates necessity of external heat-sink up tos a total output power of 30W. This productsatisfies both needs for drastic downsizing, low-profile structures and many function, high quality playback of sound system.
