LM4960 Piezoelectric Speaker Driver
General Description
The LM4960 utilizes a switching regulator to drive a dual audio power amplifier.
It delivers 24VP-P mono-BTL 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. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4960 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The LM4960 features a low-power consumption externally controlled micropower shutdown mode. Additionally, the LM4960 features and internal thermal shutdown protection mechanism along with a short circuit protection. The LM4960 i
