The ADP1031 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. Additionally, the ADP1031 contains four, high speed, serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel-to-channel applications where low power dissipation and a small solution size are required.
Key Features
► Wide input supply voltage range: 4.5 V to 60 V
► Integrated flyback power
► Generates isolated, independent bipolar outputs and factory programmable buck output
• VOUT1: 21 V, 24 V, or 6 V to 28 V
• VOUT2: 5.15 V, 5.0 V, or 3.3 V
• VOUT3: −24 V to −5 V
Applications
► Industrial automation and process control
► Instrumentation and data acquisition systems
► Data and power isolation
The ADP1031CP-EVALZ is a fully featured evaluation board that demonstrates the functionality of the ADP1031 dc-to-dc converters and the isolated data channels.
Users can evaluate ADP1031 device measurements, such as line regulation, load regulation, and efficiency with the evaluation board. The board also assists in evaluating the functionality of the isolated digital channels. Device features including oscillator synchronization, soft start, power good monitoring, sequencing, and slew rate control can be demonstrated on the evaluation board.
Each board model in the evaluation kit has a different output configuration. Only one board model is included in the kit but users can order from five different board models to fit their application needs.
