3. For most applications the LED current will be within 8% over the duty cycle range specified. Duty cycle accuracy is also dependent on
4. Refer to figure 6 for the device derating curve.
5. Test condition for SOP-8L and MSOP-8L: Device mounted on FR-4 PCB, 2”x2”, 2oz copper, minimum recommended pad layout on top layer
and thermal vias to bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.
propagation delay. Smaller size inductors can be used but LED current accuracy may be greater than 8% at extremes of duty cycle. This is
most noticeable at low duty cycles (less than 0.1) or when the input voltage is high and only one LED is being driven.
The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not
be exceeded under any condition.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken
when handling and transporting these devices
