DC2909A showcases the LTC4284 high power, negative hot swap controller with telemetry and EEPROM in a –48V, 31A (1500W) application. DC2909A is configured for parallel mode, which offers reliable low cost hot plug solution for high power systems where input steps are imminent.
Included on 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 three I2C interfaces, providing instant access to voltage, current, power, energy, fault log, and board temperature data.
