The ISL6421A is a highly integrated solution for providing power and control signals from advanced set-top box (STB) units to the satellite dish low-noise block (LNB) down convertor.

The ISL6421A is a highly integrated solution for providing power and control signals from advanced set-top box (STB) units to the satellite dish low-noise block (LNB) down convertor.

This new power and control IC offers high integration to reduce space and costs, high power efficiency to reduce power dissipation and heat, and high reliability to ensure long service in customer premises equipment.

The new ISL6421A contains both a high-efficiency current-mode boost PWM convertor and a low-noise linear regulator, along with the circuitry required for I2C device interfacing and for providing DiSEqCT standard control signals to the LNB.

The ISL6421A is available now.

The suggested resale price in 100- to 999-unit quantities for the ISL6421AER is $2.50 each in near-chip-scale 32-pad 5 x 5mm quad flat no-lead (QFN) packages.

ICs are available on tape and reel.
