LR6311

3 Watt Mono Filter-Free Class-D Audio Power Amplifier

Features

ꢀ Efficiency With an 8-Ω Speaker:

88% at 400 mW

80% at 100 mW

ꢀ 2.6mA Quiescent Current

ꢀ 0.4µA Shutdown Current

ꢀ Optimized PWM Output Stage Eliminates LC Output Filter

ꢀ Internally Generated 250-kHz Switching Frequency Eliminates Capacitor and

Resistor

ꢀ Improved PSRR (−75 dB) and Wide Supply Voltage (2.5 V to 5.5 V) Eliminates

Need for a Voltage Regulator

ꢀ Fully Differential Design Reduces RF Rectification and Eliminates Bypass

Capacitor

ꢀ Improved CMRR Eliminates Two Input Coupling Capacitors

ꢀ Available in space-saving package: 9-bump WLCSP

General Description

ss-D audio power amplifier in

The LR6311 is a 3-W high efficiency filter-free cla

a wafer chip scale package (WCSP) that requires only three external components.

Features like 88% efficiency, −75dB PSRR, and improved RF-rectification

immunity make the LR6311 ideal for cellular handsets. In cellular handsets, the

earpiece, speaker phone, and melody ringer can each be driven by the LR6311.

Applications

ꢀ Mobile phone、PDA

ꢀ MP3/4、PMP

ꢀ Portable electronic devices
