Supply ADI DC1717B Demonstration Circuit, LTC4417 Prioritized PowerPath™ Controller Evaluation Board

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the full range of ADI evaluation boards/development kits, including the DC1717B (Demonstration Circuit): LTC4417 Priority PowerPath™ Controller Evaluation Board. Product details are as follows:

【ADI】Demonstration Circuit DC1717B employs the LTC4417 to arbitrate between three input power rails, selecting the highest-priority active power source to supply the load. Power rail priority is defined by the input connections (V1-V3). Each power rail features overvoltage and undervoltage thresholds set by external resistors. Should the highest priority power rail voltage exceed its defined window (overvoltage or undervoltage), the next highest priority (available) power rail is enabled to supply the load. Two or more LTC4417 devices may be cascaded to switch between more than three power cabinets.

DC1717B Product Details:
Mainboard Name: DC1717B
Core Controller: LTC4417 Priority PowerPath™ Controller
Primary Function: Arbitrates priority among three input power supplies, automatically selecting the highest-priority active power source to supply the load
Input Power Supply Design: Connects to V1: 12V, V2: 5V, V3: 8V (each input's effective range is approximately ±20%)
Priority Sequence: V1 (Highest) → V2 → V3 (Lowest)
Protection Features: Overvoltage (OV) and Undervoltage (UV) thresholds set via external resistors; ±42V input transient protection
Status Indication: Includes logic and LEDs providing visual operational status information
Auxiliary Voltage Input: 6V to 24V
Maximum load current: 2A (limited by MOSFET performance)

Scalability: Two or more LTC4417 devices may be cascaded to support more than three power supply channels

The DC1717B is designed to operate from 12V, 5V, and 8V inputs applied to the V1, V2, and V3 ports respectively. Each power supply has an effective range of ±20%, set by the OV and UV comparators and their associated resistor dividers. V1 has the highest priority, V3 the lowest. When the highest priority input is within its effective range, that input is selected to supply the output. The V1, V2, and V3 inputs feature ±42V input glitch protection. The maximum load current is 2A, limited by MOSFET performance.

The DC1717B evaluation board is ideally suited for systems and equipment demanding high power supply reliability, including:
Industrial handheld instruments
High availability systems
Battery backup systems
Servers and computer peripherals
