Texas Instruments LP87524JRNFRQ1
The LP87524B/J/P-Q1 is designed to meet the power management requirements ofthe latest processors and platforms in various automotive power applications. The device containsfour step-down DC-DC converter cores, which are configured as4 single phaseoutputs. The device iscontrolled by an I2C-compatible serial interface and by enablesignals.
The automatic PFM/PWM (AUTO mode) operation maximizes efficiency over a wideoutput-current range. The LP87524B/J/P-Q1 supports remotevoltage sensingto 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 beforced to PWM mode and also synchronized to an external clock to minimize the disturbances.
The LP87524B/J/P-Q1 device supports load-current measurement without theaddition of external current-sense resistors. In addition, the LP87524B/J/P-Q1 supportsprogrammable start-up and shutdown delays and sequences synchronized to enable signals. Thesequences can also include GPIO signals to control external regulators, load switches and processorreset. During start-up and voltage change, the device controls the output slew rate to minimizeoutput voltage overshoot and the in-rush current.
