L5955 - Multiple multifunction voltage regulator

General Description

The L5955 is an integration of three high side drivers, six regulators and two stand-by regulators with RESET function developed to provide the power to a complete audio system.

The outputs of the IC are controlled by I2C bus and Enable pin.

Key Features

  • 2 stand-by regulators: 3.3V (125mA) 1.5V (300mA) 6 regulators: 10V (40mA) 8.5V (200mA) 3.3V (850mA) 8/10V (1A) 5/3.3/1.8V (200mA) 1.8/2.5V(200mA) All regulators are low dropout outputs The different outputs voltage are controlled by I2C Bus. Reg3 on/off controlled by enable Reg1, Reg2, Reg4, Reg5, Reg6 on/off controlled by I2CBus. 3 high side drivers: 2A (HSD1) 0.45A (HSD2 & HSD3) No external charge pump capacitors are required Stand-by mode controlled by EN pin for I2C Bus and Reg1, Reg2.
