Description
General part information
LP87332 Series
The LP87332D-Q1 is designed to meet the power management requirements of the latest processors and platforms in automotive camera and radar applications. The device has two step-down DC/DC converters, two linear regulators, and two general-purpose digital-output signals. The device is controlled by an I2C-compatible serial interface and by an enable signal.
The automatic PWM/PFM (AUTO mode) operation gives high efficiency over a wide output-current range. The LP87332D-Q1 supports remote voltage sensing to compensate IR drop between the regulator output and the point-of-load (POL), thus improving the accuracy of the output voltage. In addition, the switching clock can be forced to PWM mode and also synchronized to an external clock to minimize the disturbances.
The LP87332D-Q1 device also supports programmable start-up and shutdown delays and sequences including GPO signals synchronized to the enable signal. During start-up and voltage change, the device controls the output slew rate to minimize output voltage overshoot and the in-rush current.
