China regulated power supply module. Gold Supplier. Shenzhen Ronghai Electronics Co. CN 3 YRS. Images are for reference only See Product Specifications. Original Manufacturer. Part Type:. New Product New from original manufacturer.
Similar Products:. More Details:. Therefore can be connected in parallel directly. So that there are higher power rise. Without the resistor divided current. Which resulted in loss of resistance of these wasteful. Why the power mosfet to run faster. Therefore is low loss and high efficiency. And better reliability. And the last reason is power mosfet easy to use. Because mosfet devices species trans-conductance is controlling drain current by control voltage at gate can connect gate directly with low power circuit.
Different from the Bipolar transistor. The issue of stability in the CAR battery provide voltage changes. Quite wide are May be lower than 11V until 15V. The change this should not affect the output voltage of circuit. The circuit feature. This switch-mode power supply or DC to DC converter provide enough output power. For power amplifiers 50W 2 pcs. The maximum current 15A typically at A. There are the cut off working when low battery voltage. For protect battery power failure can not start the car.
It also has over heat protection circuit. Since inside CAR temperature was already high. Especially when it is sunny and not cold air. If the volume is too loud. May be the case until the temperature the circuit damage. To protect. When temperatures drop, so continue to work normally. The importance parts of this circuit is a pulse width modulator IC — LM By have IC4 and IC5 are a buffer circuit.
The oscillated frequency is set by R7 and C2 that high as double times of the switching frequency. In the buffer circuit include IC4 and IC5 by 4 gate digital are parallel together, to enough to driver mosfet.
Which the power mosfet is each paralleled side of 2 pcs. See: 36 Hobby Electronic Projects. Which is primary coil of transformer T1. The coil of N3,N4 is the secondary.
Which has amount of turn than the primary coil to step up voltage rise. The capacitor C4 and Diode D3 act as a soft start system to partially started operation of the circuit. Next, we see the transistor Q5 and Q6 are circuit to controlled the working more,and act on-off working of circuit that high current.
