LC-24LE210 
LC-24LE220
The K24C02C is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This NVM memory is as-
sociated to the MAIN MICRO. This EEPROM chip stores the data structure used to carry confi guration information for 
optimal use of a display (EDID data) when use a HDMI signal input.
•  IC 1006 : NVM of settings and HDCP data 
Part number: IC M24C64 
Sharp code: VHIM24C64WN-1Y
•  IC 8102 : Power supply USB port protection 
Part number: AAT4614IGU-2-T1
Sharp code: RH-IXD187WJZZY
The AAT4614 SmartSwitch is a current limited P-channel MOSFET power switch designed for high side load switching 
applications. This switch operates with inputs ranging from 2.4V to 5.5V, making it ideal for both 3V and 5V systems. An 
integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of 
regulation. Reverse current blocking is provided to protect the load switch from reverse current potentials while the device is 
shutdown. The AAT4614 is also protected from thermal overload which is limited by power dissipation and junction tempera-
tures. Current limit threshold is programmed with a resistor from SET to ground and has been adjusted for levels up to 1.1A.
Power supply Unit ICs:
• U101: PWM controller IC for 12V & 5.75V
   Part number: FAN6753
The highly integrated FAN6753 PWM controller provides several features to enhance the performance of fl yback converters.
To minimize standby power consumption, a proprietary adaptive green-mode function provides frequency modulation at 
light-load conditions. To avoid acoustic-noise problems, the minimum PWM frequency is set above 22KHz. This green-mode 
function enables the power supply to meet international power conservation requirements. With the internal high-voltage 
startup circuitry, the power loss due to bleeding resistors is also eliminated. FAN6753 integrates a full-range frequency-hop-
ping function internally that helps reduce EMI emission of a power supply with minimum line fi lters. Its built-in synchronized 
slope compensation achieves stable peak-current-mode control. 
FAN6753 provides many protection functions. In addition to cycle-by-cycle current limiting, the internal open-loop protection 
circuit ensures safety should an open-loop or output short-circuit failure occur. 
• U501: PWM standby controller IC for 5Vs
   Part number: A6069H
The STR-A6069 is power ICs for switching power supplies, incorporating a power MOSFET and a current-mode type PWM 
controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal 
operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply 
systems with few external components.
• U901: LED Driver controllers
   Part number: MP3389
The MP3389 is a step-up controller with 12-channel current sources designed for driving the WHITE LED arrays for large 
size LCD panel backlighting applications. The MP3389 uses current mode, fi xed 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 MP3389 regulates the current in each LED string to the programmed value set 
by an external current setting resistor. The MP3389 applies 12 internal current sources for current balance. And the current 
matching can achieve 2.5% regulation accuracy between strings. Its low 600mV regulation voltage on LED current sources 
reduces power loss and improves effi ciency. PWM 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.
