High-Power White LED Driver

www.DataSheet4U.com YB1519 High-Power White LED Driver Features „ 2V to 16V Input Voltage „ 40V Maximum Output Voltage „ Drive up to 18 White LEDs „ Adjustable Inductor Current „ 1μs Constant Off-time PFM Control „ 1KHz to 100KHz PWM Dimming Control Description The YB1519 is a high-power boost converter. An adjustable current limit, wide range of input voltage, and up to 40V of switch voltage are designed to drive white LEDs back-lighting for large LCD panel. It can drive up to 10 LEDs in series or 18 LEDs in parallel/series configuration. The wide application VIN range makes YB1519 suitable for many types of battery applications such as Li-ions, Alkaline, or Sealed Lead Acid batteries. The adjustable inductor current optimizes the performance for different output drive capability by an external resistor. The LED current is set by a resistor connected to FB pin. The On/Of duty with clock frequency from 1K to 100KHz at EN pin can control the LED brightness Applications „ High Power WLED Backlight Solution „ LCD Monitor „ LCD TV „ Car TV, Portable DVD „ GPS navigation system „ Handheld Game Typical Application Circuit VIN = 6 to14V 10uF 16V 22uH SL12 VIN LX EN Bypass Iset LX 4.7uF 35V 36V BZV55-B 36 YB 1519 FB 2K 10nF 6.3V 10K AGND PGND R FB 60OHM Figure 1.
