Component open/short faults
Description
The A6211 is a single IC switching regulator that provides
constant-current output to drive high-power LEDs. It integrates
a high-side N-channel DMOS switch for DC-to-DC step- down
(buck) conversion. A true average current is output using a
cycle-by-cycle, controlled on-time method.
Output current is user-selectable by an external current sense
resistor. Output voltage is automatically adjusted to drive
various numbers of LEDs in a single string. This ensures the
optimal system efficiency.
LED dimming is accomplished by a direct logic input pulse
width modulation (PWM) signal at the enable pin.
The device is provided in a compact 8-pin narrow SOIC package
(suffix LJ) with exposed pad for enhanced thermal dissipation.
It is lead (Pb) free, with 100% matte tin leadframe plating.
Package 8-pin SOICN with exposed
thermal pad (suffix LJ):
Applications:
• General Illumination
• Scanners and multi-function printers (light bars)
• Architectural lighting
• Industrial Lighting
• Display case lighting / MR16
