Simultaneous Tracking at Power Up and Power Down
Vin=12V, Vo=1.8V, Io=8A, Room Temperature, No Air Flow
In order to run the IR3841 in the simultaneous tracking mode, the following steps should be
- Remove R16 from the board.
- Set the value of R14 and R28 as R2 (4.02K) and R3 (2.55K), respectively.
- Connect the controlling input across SEQ and AGND test points on the board. This voltage
- The controlling input should be applied after the SS pin is clamped to 3.0V.

taken:
should be at least 1.15 time greater than Vo. For the following test results a 0-3.3V source is
applied to SEQ pin.
