The LT8740 is a two-channel programmable device power supply (DPS) with very high efficiency, integration, and performance. The part consists of two switching power supplies providing up to ±2.2A of DC drive current each at output voltages spanning 30V. Current sensing resistors are integrated, supporting accurate output current measurement in ranges spanning ±6.75μA to greater than ±2.2A. A linear drive stage is also included, allowing no-switching ripple DC output drive of up to ±27.5mA. DC output currents in excess of ±2.2A can be achieved by paralleling or ganging multiple DPS channels and/or devices.
The LT8740 also includes the required ADCs and DACs to set the programmable output, regulated under digital PID control, and clamp the output current and voltage. Output voltage and current can be measured digitally using the internal ADCs.
Open-drain alarm outputs are provided for overcurrent, overtemperature, or other programmable fault events. The DPS functions are controlled through a simple serial interface running at clock speeds of up to 40 MHz.
