Delivering MORE for our Customers

PMBus Solution

TI’s unique industry-standard PMBus solution completes your design needs from input protection and control to multiphase power conversion. These PMBus-compatible products are scalable across the entire power chain, thereby accelerating design time to market and ensuring interoperability. This PMBus solution provides real-time telemetry and on-the-fly configurability - which improves system intelligence and increases system utilization.

Key Solution Features:

  • Power Management and Protection IC PMBus solution – provides  input protection and telemetry giving customers input power health information and configurable protection while the power supply’s communication allows for configuration and monitoring.
  • TPS40422 – dual-output synchronous buck controller, can also be configured for a single, two-phase output. Its wide input range can support 5-V and 12-V intermediate buses. Voltage, current limit and sequencing configurable over the PMBus
  • Ultra-low-power MCU for mixed signal control – offers 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs. Memory options to allow for complete PMBus stack implementations
