White/Blue LED Driver for Li-Io Battery ApplicationsGENERAL 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 brightness through EN pin
¨ Supply voltage range 2.7V~6.0V
¨ 0.1uA standby current
APPLICATIONS
¨ Small Size Color LCD Backlights
¨ Mobile Phone, Smart Phone, PDA etc. Backlights
