Main features:

• 2-wire I²C ™ compatible serial interface: control (write) and status (read).
• LNB voltages (8 programmable levels) compatible with all current standards, including Japanese domestic models.
• Switching power converter for minimal dissipation.
• Built-in converter switches and current sensing.
• Provides up to 700mA of charging current.
• The static current limiting circuit allows full current at start-up and the output transition 13 → 18 V; reliably starts a wide load range.
• The push-pull output stage minimizes 13 → 18 V and 18 → 13 V output transition times for highly capacitive loads.
• Rise / fall time adjustable via an external synchronization capacitor.
• The built-in tone oscillator, factory set to 22 kHz, makes it easy to encode DiSEqC ™ tone, even when empty.
• Four methods of tone generation at 22 kHz, via I²C ™ data bits and / or an external pin.
• Auxiliary modulation input.
• LNB overcurrent with timer.
• Diagnosis of output voltage level, UVLO input power supply.
