TK11880FTL-G
(SON3024-8)
DESCRIPTION
The TK11880FTL-G is a step-up DC-DC converter designed for White LED driver applications, using constant frequency PWM architecture, with the following built in: a very high current switching
transistor 0.
6A peak), a high speed oscillator (1.
0MHz), a switch over current detector, a low voltage reference (VRef=0.
495V), an error amplifier, a PWM comparator, a zener diode for open-circuit protection and ON/OFF control.
TK11880FTL-G can drive up to six White LEDs in series.
This IC works with a very wide operation supply range (2.
65V~10V) and the adjustable output voltage can be set as high as 24.
5V.
