This document provides a comprehensive user guide for the evaluation boards of the ADP5023, ADP5024, ADP5034, and ADP5037 Micro Power Management Units (PMU). It details the hardware features, including standalone capability and cascading options, along with general descriptions of the devices available in a 24-lead LFCSP package. The guide covers both three-channel and four-channel configurations sharing common PCB evaluation boards.
| Package Type | 24-lead 4 mm × 4 mm LFCSP package |
|---|---|
| Input Voltage Range (Bucks) | >2.3 V to <5.5 V |
| Input Voltage Range (LDOs) | V OUT LDO + 0.5 V or 1.7 V ... to 5.5 V |
Each channel has its own enable pin which must be pulled high to enable that channel.
The buck output voltage is set through external resistor dividers connected to the feedback pin.
Regulators operate in forced PWM mode when the MODE pin is high, and automatic PWM/PSM mode when low.
