DLD101 - 1A rated linear mode constant current LED driver fron Diodes Inc.
 |
The DLD101 is a 1A |
It can also be used for low cost applications that require DC current regulation.
The DLD101 has been designed primarily for solid state lighting applications, to be used as a current sink circuit solution for LEDs. It features a N-channel MOSFET capable of 1A drive current and a prebiased NPN transistor (which allows direct connection to the base, or via a series base resistor).
Description
The DLD101 linear constant current driver is rated up to 1A and the LED current is programmed with one external resistor, offering a low cost, space saving LED drive solution.
DFN, flat, no lead package
- Saves board space, allowing for higher integration of PC board
DFN package - highly thermally efficient
- Provides higher power dissipation than relatively comparable SOT-23 form factor
1A current capability
- High drain current MOSFET element for increased light intensity output of the LEDs and lower bias current than provided by BJT pass elements
Uses unique PBT or double base connection BJT to incorporate bias resistors into package
- Integrates resistors and provides added circuit flexibility. E.g. can attach external capacitor across base resistor
Current set with one external resistor
- Lower part count and lower total cost compared to other devices
Applications
- Flashlights
- Emergency lights
- Garden lights
- LED lights
- Signage
- Back lighting applications
