Yes, but it needs current sensing. Some other chips have additional pin where you set reference input voltage to set variable cycle by cycle limit. As you change this voltage, current limit is changed.

Very nice....I was thinking you could build a very efficient LAB PSU with this - 0.9 to 50V....but you'd have to do current limiting externally....you could maybe do something using the SS (soft start) pin.

It is good to see one more vendor offering this solution. Next, we need to see, who will keep inductor inside!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
