DC/DC converters are an electronic device used to convert a direct current (DC) into another DC voltage. The NMK1509SC converter is becoming increasingly popular due to its compact size, low power consumption and wide range of input and output voltages. This article will explore the application field and working principle of the NMK1509SC converter.
Application Field
The NMK1509SC converter is suitable for a variety of application areas such as telecommunications, automotive electronics, industrial control systems, and computer peripherals. As a general-purpose DC/DC converter, this device can accept input voltages of 3V to 36V and output voltage range of 5V to 30V. Furthermore, its operating temperature range is -30ºC to +85ºC and its working efficiency is up to 93%.
This device is also designed specifically to meet the demands of certain application with its OVP (Over Voltage Protection), OTP (Over Temperature Protection) and surge protection functions. For example, for industrial applications, it can provide regulated output voltages that can contain large transients. In addition, due to an advanced ripple rejection technique, the NMK1509SC is ideal for use in noise-sensitive systems.
Working Principle
The NMK1509SC is a step-down switching voltage converter, which means it reduces the input voltage to the desired output voltage. The device integrates a phase-shift full-bridge converter and an output line PWM (Pulse-Width Modulation) regulator, together with several protection circuits. The converter synchronously rectifies the input voltage to produce a high voltage DC voltage, then the rectified voltage is stepped down by the output regulator to produce the desired output voltage.
When the output transistor is turned on, the switch drives the primary side of the transformer. The primary current slowly rises and all the windings of the transformer couples energy to the secondary side. Then the output voltage is rectified with two diode and filtered by an output capacitor. When the primary current reaches its maximum, the switched is turned off and the output transistor is then turned on, draining the energy remaining in the transformer and providing the output voltage.
Moreover, the control circuit provides pulse width modulation to control the output voltage. When the output voltage increases, a feedback voltage is generated and compared to a reference voltage. The control circuit then generates a signal that controls the output transistor to keep the output voltage at a stable value.
To ensure safe operation, the circuit includes many protection features, such as soft-start, over-load protection, over-voltage protection, and short-circuit protection. These features make the NMK1509SC suitable for applications in harsh and noise-sensitive organs.
In conclusion, the NMK1509SC converter is a versatile and powerful device. Its features make it suitable for a variety of applications, from telecommunications to automotive electronics. Furthermore, its advanced protection features guarantee its safe operation and long-term reliability.
