Do we have document about the loop respond speed of UCD3138?
Customer condition: 350kHz switch frequency, current mode.
How much the BW can reach?

Based on your comments, how can we prove to customer that loop latency of UCD3138 is fast enough?
But It is hard to evaluate the BW can be reached, this is determined by the plant design and compensator design.
Whether we have similar current mode reference design which use UCD3138? Thanks.
The core of UCD3138x digital power controller are the digital control loop peripherals, also known as Digital Power Peripherals (DPP) that are used for controlling the high-speed voltage/current loops, caused the control loop are implemented with hardware, the loop latency is faster than the general purpose MCU.
Could you clarify the applications, power level and input/output information?
