MAX1778/MAX1880–MAX1885  
Quad-Output TFT LCD DC/DC  
Converters with Buffer  
General Description  
Features  
● 500kHz/1MHz Current-Mode PWM Step-Up  
Regulator  
The MAX1778/MAX1880–MAX1885 multiple-output  
DC-DC converters provide the regulated voltages required  
by active matrix thin-film transistor (TFT) liquid crystal  
displays (LCD) in a low-profile TSSOP package. One  
high-power step-up converter and two low-power charge  
pumps convert the 2.7V to 5.5V input voltage into three  
independent output voltages. A built-in linear regulator and  
VCOM buffer complete the power-supply requirements.  
• Up to +13V Main High-Power Output  
±1% Accurate  
• High Efficiency (91%)  
● Dual Regulated Charge-Pump Outputs (MAX1778/  
MAX1880–MAX1882 only)  
• Up to +40V Positive Charge-Pump Output  
• Up to -40V Negative Charge-Pump Output  
The main step-up converter accurately generates an  
externally set output voltage up to 13V that can supply the  
display’s row/column drivers. The converter’s high switch-  
ing frequency and current-mode PWM architecture provide  
fast transient response and allow the use of small low-  
profile inductors and ceramic capacitors. The low-power  
BiCMOS control circuitry and internal 14V switch (0.35Ω  
N-channel MOSFET) enable efficiencies up to 91%.  
● Low-Dropout 40mA Linear Regulator (MAX1778/  
MAX1881/MAX1883/MAX1884 only)  
• Up to +15V LDO Input  
● Optional Higher Current with External Transistor  
● 2.7V to 5.5V Input Supply  
● Internal Supply Sequencing and Soft-Start  
● Power-Ready Output  
The dual low-power charge pumps (MAX1778/MAX1880/  
MAX1881/MAX1882 only) independently regulate one  
● Adjustable Fault-Detection Latch  
● Thermal Protection (+160°C)  
positive output (V  
) and one negative output (V  
POS  
).  
NEG  
These low-power outputs use external diode and capaci-  
tor stages (as many stages as required) to regulate output  
voltages up to +40V and -40V. A unique control scheme  
minimizes output ripple as well as capacitor sizes for both  
charge pumps.  
● 0.1μA Shutdown Current  
● 0.7mA IN Quiescent Current  
● Ultra-Small External Components  
● Thin TSSOP Package (1.1mm max height)  
A resistor-programmable, 40mA, low-dropout linear  
regulator (MAX1778/MAX1881/MAX1883/MAX1884 only)  
provides preregulation or postregulation for any of the  
supplies. For higher current applications, an external  
transistor can be added. Additionally, the VCOM buffer  
provides a high current output that is ideal for driving the  
capacitive backplane of TFT LCD panels. The VCOM  
buffer’s output voltage is preset with an internal 50%  
resistive-divider or can be externally adjusted for other  
voltages.
