Multiple-Output Power-Supply  
Controllers for LCD Monitors  
0/MAX531  
General Description  
Features  
The MAX1530/MAX1531 multiple-output power-supply  
controllers generate all the supply rails for thin-film tran-  
sistor (TFT) liquid-crystal display (LCD) monitors. Both  
devices include a high-efficiency, fixed-frequency,  
step-down regulator. The low-cost, all N-channel, syn-  
chronous topology enables operation with efficiency as  
high as 93%. High-frequency operation allows the use  
of small inductors and capacitors, resulting in a com-  
pact solution. The MAX1530 includes three linear regu-  
lator controllers and the MAX1531 includes five linear  
regulator controllers for supplying logic and LCD bias  
voltages. A programmable startup sequence enables  
easy control of the regulators.  
o 4.5V to 28V Input Voltage Range  
o 250kHz/500kHz Current-Mode Step-Down Converter  
Small Inductor/Capacitors  
No Sense Resistor  
o Three Positive Linear Regulator Controllers  
One Positive and One Negative Additional  
Controller (MAX1531)  
Small Input and Output Capacitors  
o Timed Reset Output  
o Uncommitted Overcurrent Protection (MAX1531)  
o Soft-Start for All Regulators  
o Programmable Input Undervoltage Comparator  
o Programmable Startup Sequencing  
The MAX1530/MAX1531 include soft-start functions to  
limit inrush current during startup. An internal step-  
down converter current-limit function and a versatile  
overcurrent shutdown protect the power supplies against  
fault conditions. The MAX1530/MAX1531 use a current-  
mode control architecture, providing fast load transient  
response and easy compensation. An internal linear  
regulator provides MOSFET gate drive and can be  
used to power small external loads.

The MAX1530/MAX1531 can operate from inputs as  
high as 28V and are well suited for LCD monitor and TV  
applications running directly from AC/DC wall adapters.  
Both devices are available in a small (5mm x 5mm),  
ultra-thin (0.8mm), 32-pin QFN package and operate  
over the -40°C to +85°C temperature range.
