3W Low EMI Class-D Audio Power Amplifier with Auto-Recovering Short-circuit Protection
GENERAL DESCRIPTION
The HM2010 is a high efficiency, low EMI, filterless Class-D audio amplifier with auto-recovering short-circuit protection. It operates from 2.7V to 5.5V supply. When powered with 5V voltage, the
HM2010 can deliver up to 3W into a 4Ω load or 1.8W into an 8Ω load at 10% THD+N. As a Class-D audio amplifier, the HM2010 Features
90% high efficiency and 75d B PSRR at 217Hz which make the device ideal for battery-powered high quality audio applications.
One of the key benefits of the HM2010 over traditional Class-D audio amplifiers is it generates much lower EMI emissions, thus greatly simplifying the system design for use in portable applications. Also included is the over-current or short-circuit protection with auto-recovery, which ensures the device be operated safely and reliably without the need for system interruption.
The HM2010 is available in 1.5mmx1.5mm COL-9L, MSOP-8L, and DFN2x2-8L package.
