Upgraded 60V and 5% accuracy cost
effective buck LED driver for 3W LEDs from Diodes Inc.
|
|
The AP8802 is a step-down
DC/DC converter designed
to drive LEDs with a constant
current. Its 60V maximum input
voltage allows up to fifteen
LEDs in series to be driven. Series connection of the
LEDs provides identical LED
currents resulting in
uniform brightness and
eliminates the need for
ballast resistors. |
The AP8802 switches at
frequency up to 500kHz. This allows the use of small
size external components,
hence minimizing the
required PCB area. The exposed pad
DFN3030-10 and SO-8-EP
high power dissipation packages enables the
AP8802 to drive larger
numbers of LEDs at
increased ambient
temperatures.
The AP8802 provides the simplest cost effective solution for driving multiple 3W LEDs
- Operating voltage range from 8 to 60V
- Up to fifteen LEDs can be connected in series hence higher output power can be
delivered.
- LED current can be up to 1A
- Good match for 3W LED system
- Soft-start function
- Reduce stress of LED to allow longer lifetime
- PWM and DC dimming
- Provide flexible scheme to users with different dimming methods
Up to 500kHz high switching frequency
- Cost effective and smaller inductor and capacitor can be used
- High power package – DFN3030-10 & SOP8-EP
- More choices to suit specific designs
