+title: TI LM3533 Complete Lighting Power Solution
+
+description: |
+  The LM3533 is a complete power source for backlight,
+  keypad, and indicator LEDs in smartphone handsets. The
+  high-voltage inductive boost converter provides the
+  power for two series LED strings display backlight and
+  keypad functions.
