LM4960 Description

The LM4960 utilizes a switching regulator to drive a dual audio power amplifier. It delivers 24VP-P monoBTL to a ceramic speaker with less than 1.0% THD+N while operating on a 3.0V power supply. The LM4960's switching regulator is a current-mode boost converter operating at a fixed frequency of 1.6MHz.
