... NUD4330MN Advance Information Three Channel Linear LED Driver The NUD4330 device is an integrated LED driver designed to replace discrete solutions for driving multiple LED arrays in DC high voltage applications (up to 200 V). It contains three independent channels capable to drive three independent LED arrays 100 mA. The LED current setting for each of the channels is made through an external low power resistor ...

... The max voltage drop is limited by the device's power dissipation for given conditions of ambient temperature and board copper area. 3. The typical thermal limit is set to 150°C so that the device shuts down when its lead temperature reaches 138°C for 1 power dissipation and 12°C/W of junction-to-lead thermal resistance. 4.

... The circuit shutdown delay (CSD) allows for low quiescent current when the device is in its non-operational state (all enables low). This is extremely important in particular for Li-Ion battery based applications (LapTops and portables). Figure 11 shows the equivalent circuit for CSD NUD4330MN PWM Signal VDS1 Vsense1 Iout1 = ...

... DS(n) The resulting total power dissipation should not exceed the PD value shown on the maximum ratings table. Power Dissipation Since the NUD4330 device is a linear device, power dissipation considerations should be taken into account. That is, the device's power dissipation listed on the sense , the minimum ...
