Description
Technical field
The invention belongs to electronic technology field more particularly to a kind of remote control High power amplifier circuits and its users
Method.
Background technology
The amplifier of general output high-power signal is in the least significant end of system at present, and output power is bigger than normal, is difficult to control,
When even output reaches more than 100W, final stage high power amplifier does not control, and the stabilization of final stage high power amplifier is by prime
Small signal amplifier ensures that prime small signal amplifier is small because of input signal, it is easy to control.But when pre-amplifier is in
When dangerous or unstable, final amplifier has the risk of damage.It is in particular in following several respects：
1）Prime small signal amplifier output signal is excessive, beyond the tolerance range of final amplifier input.
2）Final amplifier operating voltage is unstable, and voltage exceeds normal range of operation.
3）From final amplifier because power supply capacitor is different, job order is not known prime.When system is powered simultaneously, prime
For amplifier because supply lines is short out, power supply capacitor capacity is small, early into normal operating conditions, and because of final amplifier power supply capacitor mistake
Big reason, final stage normal work can be later than prime, when prime amplifier output power signal, fragile final amplifier.
The content of the invention
The present invention provides a kind of remote control High power amplifier circuits and its application methods in order to solve the above problem.
The present invention is achieved through the following technical solutions：
A kind of remote control High power amplifier circuits, including high power amplifier and power supply, the power supply connects
Power management chip is connected to, power management chip exports VGS voltage signals to high power amplifier, and the control of VGS voltage signals is big
The on off state of power amplifier；The power management chip is equipped with Enable Pin, the remote control high power amplifier electricity
Road further includes remote control terminal, and remote control terminal controls what power management chip exported by sending enable signal to Enable Pin
VGS voltage signals.
It is further to improve, which is characterized in that the power management chip is connected by regulation resistance and high power amplifier
It connects.
Further to improve, the power management chip is TPS5410 chips.
A kind of application method of remote control High power amplifier circuits, includes the following steps：
Step 1）Power supply is powered to high power amplifier；
Step 2）Remote control terminal exports enable signal, and power management chip output VGS voltage signals make at high power amplifier
In normal condition；
Step 3）Input signal, high power amplifier normal work are added in high power amplifier；In the event of failure, remote control
Enable signal and input signal are closed in end, and power management chip is exported without VGS voltage signals, and high power amplifier does not work, and is located
In protection；
Step 4）Input signal is closed, remote control terminal closes enable signal, and power supply stops supplying to high power amplifier
Electricity.
Compared with prior art, the present invention has the following advantages：
The setting of prime small signal amplifier is eliminated, power management chip reaches control final stage amplification by controlling VGS voltages
The effect of device work can effectively prevent the tolerance range that signal exceeds final amplifier input, protect final amplifier.Power supply
Managing chip can also make circuit obtain remote control function.The voltage transformation of VDD branches is changed to VGS electricity by power management chip
Pressure so ensures amplifier VDD after the power is turned on, and VGS may just be powered on, and ensure that the normal electric sequence of amplifier.
