Application Information (cont.)
Reducing Output Ripple
Peak to peak ripple current in the LED(s) can be reduced, if required, by shunting a capacitor, Cled, across the LED(s) as shown below:

package power dissipation limits. The graph below gives details for power derating. This assumes the device to be mounted on a (25mm) PCB
ZXLD1356
A value of 1μF will reduce the supply ripple current by a factor three (approx.). Proportionally lower ripple can be achieved with higher capacitor
values. Note that the capacitor will not affect operating frequency or efficiency, but it will increase start-up delay, by reducing the rate of rise of
LED voltage.
By adding this capacitor the current waveform through the LED(s) changes from a triangular ramp to a more sinusoidal version without altering
the mean current value.
Operation at Low Supply Voltage
Below the under-voltage lockout threshold (V SD ) the drive to the output transistor is turned off to prevent device operation with excessive on-
resistance of the output transistor. The output transistor is not full enhanced until the supply voltage exceeds approximately 17V. At supply
voltages between V SD and 17V care must be taken to avoid excessive power dissipation due to the on-resistance.
Note that when driving loads of two or more LEDs, the forward drop will normally be sufficient to prevent the device from switching below
approximately 6V. This will minimize the risk of damage to the device.
Thermal Considerations
When operating the device at high ambient temperatures, or when driving maximum load current, care must be taken to avoid exceeding the
