ADP5140WACCZ-R7

ADP5140WACCZ-R7 is a power management IC for automotive applications. It integrates four high-performance, synchronous, step-down buck regulators (BUCK1 to BUCK4), one boost regulator, and seven low-noise, low dropout (LDO) regulators (LDO1 to LDO7). The seven LDOs provide a clean output voltage for the system. LDO5 provides an ultralow noise output that can be used to power noise-sensitive loads. The four buck regulators run at 90° out of phase to reduce the input ripple current and the input capacitor size, which lowers the system electromagnetic interference (EMI). All regulators integrate internal compensation to simplify the design. The internal soft-start circuitry and power-up sequencing reduce the input inrush current. The application includes advanced driver assistance (ADAS), automotive electronics, infotainment systems, and industrial and instrumentation.
