TK11850L Description
The TK11850L is a pulse skipping step-up DC-DC converter IC designed for White LED driver applications with the following built in: a very high current switching transistor (400 mA peak), an inductor current limit detector, low voltage reference (Vref = 0.5 V), high speed oscillator, an error parator, a rectifier diode (for small power output) and an ON/OFF control. The IC works with a very wide operating supply...
