ISL9491ERZ规格书详情
These devices are designed for supplying power and
control signals from advanced satellite set-top box (STB)
modules to the low noise blocks (LNBs) of single antenna
ports. Each device consists of a current-mode boost
converter and a low-noise linear regulator along with the
circuitry required for tone injection and pin controllable
interface. The device makes the total LNB supply design
simple, efficient and compact with low external
component count.
The current-mode boost converters provide the linear
regulator with input voltage that is set to the voltage at
the VOUT pin plus a minimal drop to insure minimum
power dissipation across the internal LDO. This maintains
constant voltage drop across the linear pass element
while permitting adequate voltage range for tone
injection.
The final regulated output voltage is available at the
cathode of the back diode to support the operation of an
antenna port for a single tuner. The outputs can be set to
various voltage level for the desired polarization
reception by means of the logic presented to the VSET0
and VSET1 pins. An EN pin is to be driven high to enable
the outputs for the PWM and linear combination; setting
EN low disables the output, forcing a shutdown mode.
The external modulation input (EXTM) can accept a tone
modulated DiSEqC command and transfer it
symmetrically to the output to meet DiSEqC 1.x protocol.
An external DiSEqC tank circuit can also be implemented
to support DiSEqC 2.x.
