Description

General part information

ADP5051 Series

The ADP5051 combines four high performance buck regulators, and a supervisory circuit with a voltage monitor, watchdog, and manual reset in a 48-lead LFCSP package that meets demanding performance and board space requirements. The device enables direct connection to high input voltages up to 15.0 V with no preregulators.Channel 1 and Channel 2 integrate high-side power MOSFET and low-side MOSFET drivers. In low-side power devices, use external NFETs to achieve an efficiency optimized solution and deliver a programmable output current of 1.2 A, 2.5 A, or 4 A.Combining Channel 1 and Channel 2 in a parallel configuration provides a single output with up to 8 A of current. Channel 3 and Channel 4 integrate both high-side and low-side MOSFETs to deliver an output current of 1.2 A.The ADP5051 supervisory circuits monitor voltage level. The watchdog timer generates a reset when the WDI does not toggle within a preset timeout period. Select manual reset functionality via the processor reset mode or system power on/off switch mode.The optional I2C interface offers flexible configurations, including adjustable and fixed output voltage, junction temperature overheat warning, low input voltage detection, and dynamic voltage scaling.APPLICATIONSSmall cell base stationsFPGA and processor applicationsSecurity and surveillanceMedical applications
