Instruction Manual
3. Sequence Timing Chart
Note) *1. ON / OFF Control Terminals (CNT ,TOG) are isolated from other terminals of this product (Floating).
Control ON
・・・・
Short the CNT and TOG terminals, or apply ext. voltage of 0 to 0.4V.
Control OFF
・・・
Open the CNT and TOG terminals, or apply ext. voltage of 1.5V to 5.0V.
Do not apply voltage greater than 5.5V to avoid over current flow into these terminals.
*2. Please remove input once and apply again, or restart control ON/OFF to reset the OVP or LVP.
*3. The terminal voltage between CNT & TOG is about 5.6V at open mode. It changes 0V when turning off input.
*4. For 5V output model, OCP method is constant current limit with latch shutdown (by LVP). It can be reset as the 2 above.
Furthermore, for 12, 15, and 24V output model, OCP method is Constant Current Limit with automatically reset.
