Overview
PT4401/2
3/4 Channel Parallel White/Blue LED Drivers
GENERAL DESCRIPTION
The PT4401/2 is a series of White/Blue LED drivers, with PT4401 capable of driving three LEDs and PT4402 driving four LEDs.
There is no external component needed, which helps to simplify the system design and lower the system cost significantly.
The circuit is optimized to provide over 90% efficiency.
The PT4401/2 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.
PT4401 is available in SOT-23-6 pac...
