The Texas Instruments LP873220RHDRQ1 is a versatile power management integrated circuit designed for automotive applications, specifically for J6 entry processors. This device integrates two high-efficiency step-down (buck) DC/DC converters and two linear regulators, providing a total of four regulated outputs.
The buck converters support an input voltage range of 2.8V to 5.5V, with output voltages adjustable from 0.7V to 3.36V and a maximum output current of 2A per channel. They feature a 2MHz switching frequency and offer programmable output-voltage slew rates from 0.5 mV/µs to 10 mV/µs, with options for spread-spectrum mode and phase interleaving for reduced EMI.
The two linear regulators operate from a 2.5V to 5.5V input and provide adjustable output voltages from 0.8V to 3.3V, each capable of delivering up to 300mA. The device includes configurable general-purpose output signals (GPO, GPO2) and supports features like I2C control, power good indication, power sequencing, thermal shutdown, and undervoltage lockout (UVLO).
Packaged in a 28-VQFN (5x5 mm) with wettable flank surface mount termination, the LP873220RHDRQ1 is AEC-Q100 qualified for automotive use, with an operating temperature range of -40°C to +125°C.
