Note 1) It is a prerequisite for this product to be mounted onto a board, thereby heat relation is done. 70% or more of the
Note 2) The third pin is check pin when it manufactures. Please install land for the converter fixation and fix on the board.
Note 3) When not using the On/Off control, keep the On/Off pin open.
Note 4) When not adjusting the output, keep the trim pin open.
Note 5) GND pin (6, 9pin) is connect inside, however to secure the performance, use it with the 2 pins connected to the
Note 6) Be sure to connect the sense pin and output pin on the board. Unless the sense pin is connected, there is a
Note 7) Do not wire a pattern right under the converter (first layer). For other layers wiring a pattern will be no problem.
Recommended Capacitor
C1=47μF x 2
C2=2.2μF ~200μF
C1 : It is unnecessary if impedance of the power supply on the input side is low enough and the power supply on input
C2 : The converter will operate without C2 because the output capacitor has built in, however, it is necessary to satisfy
+Vin
heat radiation is done from the GND pin(6, 9pin) and the rest is done from the +Vin pin and +Vout pin. Take space
of the pattern as much as possible and design the board to make radiation easy. (Please use that surface
