NMH0505DC

DC-DC converters are widely used in electronic circuits because of their cost and space-saving advantages, and the NMH0505DC is no exception. This device takes a single input voltage, typically from a battery, and produces a wide range of regulated output voltages that are adjustable from zero to the input voltage. It is available in three basic configurations – the basic step-up converter (the‘ boost’ type) which is used for raising low voltage or current sources, the step-down (the ‘bucks’ type) for reducing high voltage supplies, and the inverting type for producing an output voltage of reversed polarity from a positive input.This particular model is ideal for low current and low voltage applications, such as battery chargers, portable medical equipment, hand-held devices, and consumer electronics. It is also suitable for solar and wind power systems. The NMH0505DC is a current mode, hysteretic, non-isolated DC-DC step-down (buck) converter that is designed to provide up to 1.5 Amps of continuous output current with a very high conversion efficiency up to 97%. The internal structure of the NMH0505DC consists of a driver circuit, a main MOSFET switch, an error amplifier, a voltage reference, a current-mode control and a power diode.The output voltage is regulated by adjusting the duty cycle of the main switch using the error amplifier and voltage reference.When the input voltage is higher than the output voltage, the main switch is turned on; when the input voltage is lower than the output voltage, the main switch is turned off.The current-mode control circuit is used to regulate the output current to the desired level by comparing the current sense voltage with the voltage reference.When the current sense voltage exceeds that of the voltage reference, the converter is switched to limit the current, and action is reversed if the current sense voltage is below the reference voltage. The NMh0505DC is also equipped with thermal protection, internal current limiting and short circuit protection for safety and reliability. The device is also an ideal choice for applications that require a wide range of voltage and current capabilities. In its basic form, the NMh0505DC can be used to generate a constant output voltage from a given input voltage. For example, if a 12V input voltage is used to produce a 5V output, then the converter will act as a step-down device and reduce the input voltage to the desired level. The converter can also be used as a voltage converter, allowing users to vary the output voltage in order to match the load requirements. For example, if the application demands a voltage that is higher than the input voltage, then the converter can be used as a step-up device to increase the output voltage until it meets the application needs. In summary, the NMH0505DC DC-DC converter is a versatile device that can be used for a variety of applications. Its small size, high efficiency and wide range of voltage and current capabilities make it an ideal choice for battery chargers, portable medical equipment, hand-held consumer devices and renewable energy applications.
