Demonstration circuit 2470A showcases the LTC4284 high power, negative Hot Swap controller with I2C energy monitor and EEPROM in a 2.5kW, −48V application. DC2470A is configured for low stress staged start, which offers the lowest cost hot plug solution for high power systems.
Included on the board is isolation for power good control pins to enable downstream power converters. LEDs indicate the presence of −48V input and output as well as the state of both supply feeds and power good signaling. High voltage layout rules are followed throughout for best long term product reliability.
Headers are provided for all three LTC evaluation interfaces, providing instant access to voltage, current and power measurements, fault logging, and board temperature.
