The LTC3880EUJ#TRPBF is a dual-output, PolyPhase DC/DC synchronous step-down switching regulator controller with an I2C-based PMBus compliant serial interface. It utilizes a constant frequency, current mode architecture and is supported by LTpowerPlay software. The device offers programmable voltage, current limit, and frequency synchronization.
Key electrical specifications include a wide input voltage range of 4.5V to 24V and an output voltage range of 0.5V to 5.4V. The output voltage accuracy is ±0.5% over temperature. It supports switching frequencies from 250kHz to 1MHz and features accurate PolyPhase current sharing for up to 6 phases.
This controller is designed for high current distributed power systems, telecom, datacom, and storage systems, as well as intelligent energy-efficient power regulation. It is available in a 40-pin QFN package suitable for surface mounting.
The LTC3880EUJ#TRPBF includes features like an integrated 16-bit ADC for telemetry readback, internal EEPROM with ECC and fault logging, and integrated powerful N-channel MOSFET gate drivers. It supports digital soft-start/stop, sequencing, margining, and OV/UV protection.
