Description
This chip is a continuous mode inductive step-down converter,
designed for driving single or multiple series connected LEDs
efficiently from a voltage source higher than the LED voltage.
The device operates from an input supply between 9V and *0V
and provides and extremally adjustable output current of up to
1A.
( Specification)
- Internal *0V high voltage NMOS switch
- LED driving current up to ~ 1A
- Single pin on/off and dimming control using DC or PWM
- Soft-start function
- Thermal shutdown protection
- SOP*8, SOP*8(EP) package
(Application)
- Low voltage halogen replacement LEDs
- Low voltage industrial lighting & Illuminated signs
- Automotive lighting & LCD TV backlighting
