TK11880FTL-G
Overview
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.
- Very wide operating voltage range (2.65 to 10V)
- 1.0MHz operation
- Internal switching transistor *
