8. Standard Connection Circuit Diagram
Note 1) It is a prerequisite for this product to be mounted onto a board, thereby heat radiatoin is done.
Note 2) When not using the ON/ OFF control, keep the On/ Off pin open.
Note 3) P-Good pin is an open drain output. When using the P-Good function, pull up the P-Good to the input voltage using the resistance.
Note 4) When not adjusting the output, keep the trim pin open.
Note 5) GND pin (5, 8pin) is connect inside, however to secure the performance, use it with the 2 pins connected to the GND line.
Note 6) Be sure to connect the sense pin and output pin on the board. Unless the sense pin is connected, there is a possibility that a
Note 7) Do not wire a pattern right under the converter (first layer). For other layers wiring a pattern will be no problem.

70% or more of the heat radiation is done from the GND pin (5, 8pin) 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 temperature
