6 / 14 page  DS_NE12S06A_05202013 6 DESIGN CONSIDERATIONS The NE12S0A0V(H)06 uses a single phase and voltage mode controlled buck topology. The output can be trimmed from 0.59Vdc to 5.1Vdc by a resistor from Trim pin to Ground. The converter can be turned ON/OFF by remote control with positive on/off (ENABLE pin) logic. The converter DC output is disabled when the signal is driven low (below 0.3V). This pin is also used as the input turn on threshold judgment. Its voltage is percent of Input voltage during floating due to internal connection. So we do not suggest using an active high signal (higher than 0.8V) to turn on the module because this high level voltage will disable UVLO function. The module will turn on when this pin is floating and the input voltage is higher than the threshold. The converter can protect itself by entering hiccup mode against over current and short circuit condition. Also, the converter will shut down when an over voltage protection is detected. Safety Considerations It is recommended that the user to provide a very fast-acting type fuse in the input line for safety. The output voltage set-point and the output current in the application could define the amperage rating of the fuse. FEATURES DESCRIPTIONS Enable (On/Off) The ENABLE (on/off) input allows external circuitry to put the NE converter into a low power dissipation (sleep) mode. Positive ENABLE is available as standard. With the active high function, the output is guaranteed to turn on if the ENABLE pin is driven above 0.8V. The output will turn off if the ENABLE pin voltage is pulled below 0.3V. Undervoltage Lockout The ENABLE pin is also used as input UVLO function. Leaving the enable floating, the module will turn on if the input voltage is higher than the turn-on threshold and turn off if the input voltage is lower than the turn-off threshold. The default turn-on voltage is 3.1V with 300mV hysteresis. The turn-on voltage may be adjusted with a resistor placed between the “Enable” pin and “Ground” pin. The equation for calculating the value of this resistor is: 8 . 0 34 . 6 34 . 6 05 . 15 _ R R V RTH EN V V V RTH EN FTH EN 3 . 0 _ _ FTH EN V _ is the turn-off threshold RTH EN V _ is the turn-on threshold R (Kohm) is the outen resistor connected from Enable pin to the GND NE10A/6A R Enable Fig. 18. UVLO setting An active high voltage will disable the input UVLO function. |
