PT4412 4通道 20mA LDO LED背光驱动IC White/Blue LED Driver for Li-Io Battery Applications GENERAL DESCRIPTION The PT4412 is a series of White/Blue LED drivers. There is no external component needed, which helps to lower the system cost significantly. The circuit is optimized to provide over 90% efficiency. The PT4412 is ideal to drive white LEDs used for Li-ion battery powered LCD displays. The LED brightness can be adjusted in real time through a PWM signal at the EN pin. The target end applications are small color LCD displays in mobile phones, smart phone, digital cameras, PDA etc. PT4412 is available in SOT23-6 package. FEATURES ¨ No external component required ¨ Fixed 20mA and 15mA sinking current ¨ Individual current sink circuit for each output to prevent short/open circuit on LEDs ¨ PTC LED current for luminosity compensation ¨ 4 channels available ¨ PWM tuned LED...
