Analog Devices Power Management Unit (PMU) for ADP5051

Evaluation Board for the ADP5051 4-Channel Power Management Unit (PMU) with Supervisory

The ADP5051 combines four high performance buck regulators and a supervisory circuit with a voltage monitor, watchdog, and manual reset.
Channel 1 and Channel 2 integrate high-side power MOSFET and low-side MOSFET drivers.
The 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.

Switching Voltage Regulators, Analog Devices

A wide range of switching regulators from Analog Devices offers operation in step-up (boost), step-down (buck), and inverting voltage modes. The regulators generate fixed or adjustable output voltage.
