AME5142AEEYADJZ
High efficiency 6 white LED driver with open LED protection
, SOT26, AME, RoHS
The AME5142 is a Boost DC/DC converter specifically designed to drive white LEDs with a
constant current. The device can drive 1 to 6 LEDs in
series or multiple strings from a Li-lon cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for
ballast resistors.

1.2MHz Fixed Switching Frequency
28V Over Voltage Protection
Over Temperature Protection
Internal Soft Start
30V Internal Switch
Drives Up to 6 LEDs from a 2.7V Supply at
20mA
Only small external Capacitors and Inductor
required
