The MP3394 is flexible for extending LED channels with two or more MP3394s in parallel while operating from a single inductor power source.  \nThe MP3394 uses current mode, fixed frequency architecture. The switching frequency is programmable by an external frequency setting resistor. It drives an external MOSFET to boost up the output voltage from a 5V to 28V input supply. The MP3394 regulates the current in each LED string to the programmed value set by an external current setting resistor. The MP3394 applies 4 internal current sources for current balance and the current matching can achieve 2.5% regulation accuracy between strings. Its low 350mV regulation voltage on LED current sources reduces power loss and improves efficiency.  \nPWM dimming is implemented with external PWM input signal or DC input signal. The dimming PWM signal can be generated internally and the dimming frequency is programmed by an external setting capacitor.  \nFEATURES  \n• 4-String, Max 200mA/String WLED Driver  \n• 5V to 28V Input Voltage Range  \n• 2.5% Current Matching Accuracy Between Strings  \n• Programmable Switching Frequency  \n• PWM or DC Input Burst PWM Dimming  \n• Open and Short LED Protection  \n• Programmable Over-Voltage Protection  \n• Cascading Capability with a Single Power Source  \n• Under Voltage Lockout  \n• Thermal Shutdown  \n• TSSOP16EP， SOIC16, SOIC20 Package  \nAPPLICATIONS  \n• Desktop LCD Flat Panel Displays  \n• Flat Panel Video Displays  \n• LCD TVs and Monitors  \nAll MPS parts are lead-free and adhere to the RoHS directive.
