Piezoelectric Speaker Driver - National Semiconductor

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 LM4960s 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 appli- cations where minimal power consumption is a primary re- quirement. 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 is unity-gain stable and CAN be configured by external gain-setting resistors.
