Dual Output LNB Supply and Control Voltage Regulator with I2C Interface for  
Advanced Satellite Set-Top Box Designs  
The ISL6405 is a highly integrated voltage regulator and  
interface IC, specifically designed for supplying power and  
control signals from advanced satellite set-top box (STB)  
Features  
• Single Chip Power solution  
- True Dual Operation for 2-Tuner/2-Dish Applications  
- Both Outputs May be Enabled Simultaneously at  
Maximum Power  
- Integrated DC-DC Converter and I C Interface  
modules to the low noise blocks (LNBs) of two antenna  
ports. The device is composed of two independent  
current-mode boost PWMs and two low-noise linear  
regulators along with the circuitry required for 22kHz tone

2
• Switch-Mode Power Converter for Lowest Dissipation  
- Boost PWMs with > 92% Efficiency  
- Selectable 13V or 18V Outputs  
generation, modulation and I C device interface. The device  
makes the total LNB supply design simple, efficient and  
compact with low external component count.  
- Digital Cable Length Compensation (1V)  
Two independent current-mode boost converters provide the  
linear regulators with input voltages that are set to the final  
output voltages, plus typically 1.2V to insure minimum power  
dissipation across each linear regulator. This maintains  
constant voltage drops across each linear pass element  
while permitting adequate voltage range for tone injection.  
2
• I C Compatible Interface for Remote Device Control  
- Registered Slave Address 0001 00XX  
- Full 3.3V/5V Operation up to 400kHz  
• External Pins to Select 13V/18V Options  
- Available with QFN Package Only  
• Built-In Tone Oscillator Factory Trimmed to 22kHz  
- Facilitates DiSEqCTM (EUTELSAT) Encoding  
The final regulated output voltages are available at two  
output terminals to support simultaneous operation of two  
antenna ports for dual tuners. The outputs for each PWM are  
set to 13V or 18V by independent voltage select commands  
• Internal Over-Temperature Protection and Diagnostics

(VSEL1, VSEL2) through the I C bus. Additionally, to  
• LNB Short-Circuit Protection and Diagnostics  
compensate for the voltage drop in the coaxial cable, the  
selected voltage may be increased by 1V with the line length  
compensation (LLC) feature. All the functions on this IC are  
• QFN Package  
- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat

controlled via the I C bus by writing 8 bits on System  
Register (SR, 8 bits). The same register can be read back,  
and two bits will report the diagnostic status. Separate enable  
commands sent on the I C bus provide independent standby  
mode control for each PWM and linear combination, disabling  
the output into shutdown mode.  
- Near Chip-Scale Package Footprint  
• Pb-free Packaging Available  
- Designated with “Z” Suffix (Refer to Note Below)  
2
Applications  
Each output channel is capable of providing 750mA of  
continuous current. The overcurrent limit can be digitally  
programmed. The SEL18V pin with QFN package allows the  
13V to 18V transition with an external pin, over-riding the I C  
input.  
• LNB Power Supply and Control for Satellite Set-Top Box

NOTES:  
1. Intersil Pb-free products employ special Pb-free material sets; molding  
compounds/die attach materials and 100% matte tin plate termination  
finish, which is compatible with both SnPb and Pb-free soldering  
operations. Intersil Pb-free products are MSL classified at Pb-free peak  
reflow temperatures that meet or exceed the Pb-free requirements of  
IPC/JEDEC J Std-020B.  
2. Tape and Reel available. Add “-T” suffix for Tape and Reel Packing Option.
