Specification Notes: 1. Exceeding 40V on the unit input could damage the unit. 2. No connection should be made between input ground and the output. 3. These are step-down devices, the maximum output open voltage is equal to the input voltage. 4. The PWM/Cont input (Pin 3) should be left open if not used. 5. Exceeding the spe.
