Programming and Development Support
- Comprehensive register map and API for I2C/SMBus and SPI control, with examples in C for common microcontrollers.
- Evaluation kit: breakout board with VIN regulator, headers for telemetry, and jumper-configured rails for rapid prototyping.
- Reference designs: power-tree examples for typical SoC/FPGA and battery-powered designs, plus layout files and Gerbers.
- Firmware tools: GUI-based power-sequencer editor to generate register sequences and configuration blobs for production programming.
Typical Application Circuit
Example Use Case — Edge AI Vision Module
- Requirements: 1.2 V core (3 A), 1.8 V I/O (1 A), 3.3 V analog (500 mA), 5 V sensor rail (200 mA), strict power-up order with sensor rails after core.
- VPMS2SM role: implement 3 buck channels (1.2 V, 1.8 V, 3.3 V) and an LDO for 5 V sensor output, program sequencing so core and I/O come up first, enable sensors only when rails are stable, monitor current for thermal throttling, and report telemetry to host for power optimization.
- Benefit: single-chip solution reduces BOM, simplifies sequencing, and gives live telemetry for power-aware workload scheduling.
CS (Current Sense): Monitors the primary current to regulate the LED output. VDD: Power supply pin for the internal control circuitry. GND: Ground reference. Comprehensive register map and API for I2C/SMBus and
