Radiation Hardened Quad Power Supply Sequencer Demonstration Board


The ISL70321SEHDEMO1Z is a Small Form Factor (SFF) board suitable for integrating onto an existing circuit board or onto a prototype system circuit. The demonstration board provides up to four sequencing events for Point-of-Load (POL) regulators powering multi-rail loads.

The ISL70321SEHDEMO1Z provides access to the IC pins for integration along with a minimum of external passives to provide decoupling, a 2:1 resistive divider on the four VM inputs, pull-ups, and the timers set to 2ms and 4ms for the delay and power-good durations, respectively.

Key Features

  • Small, compact design
  • Easy to integrate into an existing circuit
  • Highly customizable


  • Power sequencing for multi-rail devices such as FPGAs, DSPs, and communications ICs
  • Power management of high-density distributed power systems and RF applications
