DC DC Converters are used for the purpose of providing reliable and efficient power transfer from AC or DC sources to the user end equipped electrical and electronic devices. This facilitates the efficient utilization of power and convenience for the user in controlling and managing their devices.The ST305HC 78 DC DC Converter by STMicroelectronics is a step up DC DC converter with integrated power MOSFETS and features a wide input voltage range of 5.5V to 60V and a maximum output voltage of 24V.

This DC DC converter is ideal for use in mobile, automotive and consumer applications, as it suits power requirements of a range of devices such as TV sets, computers, cameras and other consumer products. As it is naturally compact and light in weight, it can be used in portable items and therefore with great ease. The ST305HC 78 also works incredibly fast, delivering a switching frequency of 800KHz.

The working principle of the ST305HC 78 DC DC Converter involves an input voltage range of 5.5 to 60V being used in order to generate an output voltage of 24V or a higher voltage as set by the user. It does this with the help of the ST integrated power MOSFET technology which works based on a process known as pulse width modulation (PWM) switching.

The system uses the forward-type switching topology and includes a power switch which is controlled by a high-frequency PWM signal, generated from a control integrated circuit (IC). When the input voltage is applied, the control IC produces a PWM signal which is used to regulate the power switch ON and OFF in a controlled manner to prevent any overvoltage or undervoltage conditions from occurring at the output. When the power switch is switched ON, the voltage on the secondary winding of the transformer is then increased, which increases the output voltage from the 24V mark.

In addition to this, a number of safety features have been implemented in order to protect the ST305HC 78 DC DC Converter from damage and to ensure that the device operates efficiently and for a long period of time. These include thermal shutdown, overvoltage protection, thermal shut-off as well as an integrated soft-start feature.The ST305HC 78 DC DC Converter is capable of delivering a maximum output current of 3A, with a peak current of 4A. Moreover, the device can be easily programmed by using a simple interface as well as a wide range of electrical characteristics can be set up in accordance with the user requirements.

All in all, the ST305HC 78 DC DC Converter is an off-the-shelf solution which offers high efficiency and reliability, as well as high EMI immunity for the applications where it is used. It is an ideal choice for delivering efficient and safe power transfer in a variety of consumer products, especially since it is also rather affordable.
