ADP5140-EVALZ Core Chip Details (ADP5140):
ADP5140 – Power Management IC for Automotive Applications
The ADP5140 integrates four high-performance synchronous buck regulators (BUCK1 to BUCK4), one boost regulator, and seven low-noise, low-dropout (LDO) regulators (LDO1 to LDO7). The buck regulators support input voltages from 2.7 V to 5.5 V, delivering output currents ranging from 2.5 A to 3 A. The boost regulator provides a fixed 5 V output with a 400 mA load current. The seven LDOs supply clean output voltages to the system, with LDO5 featuring low noise characteristics for powering noise-sensitive loads.
ADP5140 Product Features:
Boost regulator: Fixed 5V output, 400mA output current range
Seven low-noise output LDO regulators
2.2MHz (typical) switching frequency
Synchronous input or output
Staggered phase between buck regulators
Integrated soft-start and compensation for all regulators
Overcurrent and thermal protection on all power rails
Two window voltage monitors
Two windowed watchdogs with pulse detection
One quality assurance monitor
Wake-up input
SPI interface for control and diagnostics
RESET, FAULT, and STATUS outputs
56-pin LGA package
