DC2116A-A

DC2116A-A demonstration circuit features the LTC4234, 20A Guaranteed SOA Hot Swap™ controller. The LTC4234 is ideally suited for compact power distribution control in 2.9V to 15V applications for hot board insertion protection, high side power switching and electronic circuit breaker functions. It provides a rich set of features to support Hot Swap applications including: 2.5% accurate undervoltage and overvoltage protection, overtemperature protection, adjustable inrush current control, adjustable, 11% accurate current limit, adjustable output voltage ramp rate, configurable for auto retry or latch off for overcurrent faults, power good and fault outputs. It is configured for a 12V application. By changing a few passive components, 2.9V to 15V applications can easily be evaluated.

• 15.2V overvoltage lockout (nominal)
• 9.2V nom undervoltage lockout (voltage falling) and 9.9V nom undervoltage lockout (voltage rising)
• 22.5A nominal output current limit
• 8200µF (nominal) maximum load capacitance
• 1.2ms or 2.0ms nominal timer expiration period
