The factory default switching frequency is preset at 350kHz typical. Analog Devices Inc. DC3082A-C comes with a PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the dongle DC1613A to the demo board. This connector provides an easy way to communicate and program the part using the LTpowerPlay® software development tool. LTpowerPlay software and I2C/PMBus/SMBus dongle DC1613A allow users to monitor real-time telemetry of input and output voltages, input and output current, switching frequency, internal IC die temperatures, power stage component temperatures, and fault logs. Programmable parameters include device address, output voltages, control loop compensation, switching frequency, phase interleaving, DCM or CCM mode of operation. These also include digital soft-start, sequencing, and time-based shutdown, fault responses to input and output overvoltage, output overcurrent, IC die, and power component overtemperature.
