HM2010

3W Low EMI Class-D Audio Power Amplifier

with Auto-Recovering Short-circuit Protection

GENERAL DESCRIPTION

FEATURES

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

. Filterless Class-D operation

. High efficiency up to 90%

. Output power at 5V supply

- 3.0W (4Ω load, 10% THD+N)

- 1.8W (8Ω load, 10% THD+N)

- 2.4W (4Ω load, 1% THD+N)

- 1.4W (8Ω load, 1% THD+N)

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 75dB PSRR at 217Hz

which make the device ideal for battery-powered

high quality audio applications.

. Low THD+N: 0.05% (typical) @ 1kHz

(VDD=3.6V, RL=8Ω, PO=0.5W)

. Low quiescent current: 2mA at 3.6V (8Ω load)

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.

. Extremely low shutdown current: 0.1µA (typical)

. High PSRR: 75dB (typical) at 217Hz

. No bypass capacitor required for the

common-mode bias

. Under-voltage lockout

. Auto recovering short-circuit protection

. Over-current & thermal overload protection

. Low EMI design

The HM2010 is available in 1.5mmx1.5mm COL-9L,

MSOP-8L, and DFN2x2-8L package.

. Available in 1.5mmx1.5mm COL-9L, MSOP-8L,

and DFN2x2-8L packages

APPLICATIONS

. Mobile Phones

. Portable Digital Assistant (PDA)

. MP3/MP4 Player
