TK11880FTL-G Product Details

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 curent 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. The white LEDs are connected in series and driven at a constant current. resulting in uniform brightness and high efficiency. The reference voltage is a very low 0.495V. achieving high efficiency operation with the constant current output. 

The ON/OFF control is built-in and the circuit culrent can be decreased when the EN pin is low (shutdown mode). The built-in zener diode can be used for open-circuit protection in case the output load i3 disconnected, such as the string of LEDs opened. The internal zener diode reduces the external component count.

The TK11880FTL-G can also be used in other applications as a step-up DC-DC converter.

The TK11880FTL-G is available in the SON3024-8 surface mount package.
