The L5962 is a very versatile device exploiting BCD technology characteristics to provide a complete set of regulated voltages covering all the needs of a car-radio set. In standby condition the device guarantees extremely low quiescent current (-40 °C < T < 85 °C) and minimum operating voltage (4.5 V using the internal low voltage start-up circuit), making it the ideal choice for car radio applications.
The L5962 is a versatile device designed for car-radio sets that integrates a step-down synchronous switching voltage regulator with multiple linear regulators. It provides regulated voltages for standby, switched linear operation, and high-side drivers, all controlled via an I2C bus.
