onsemi NCP2820
The NCP2820 is a cost−effective mono Class−D audio power amplifier capable of delivering 2.65 W of continuous average power to 4.0 W from a 5.0 V supply in a Bridge Tied Load (BTL) configuration. For cellular handsets or PDAs it offers space and cost savings because no output filter is required when using inductive tranducers. With more than 90% efficiency and very low shutdown current, it increases the lifetime of your battery and drastically lowers the junction temperature.| Part No. | NCP2820 |
