L296PHT is a DC to DC switching regulator developed by STMicroelectronics. It is designed to provide stable power output levels for industrial and consumer applications that require high performance and low noise. The device is designed to be used in low power requirements such as low-current, low-voltage, low-power electronics applications like consumer and consumer goods, industrial controls, etc.

Application Field

The L296PHT is a monolithic switching regulator with integrated power MOSFETs, providing high efficiency and reduced noise operation. It offers low I_MAX and low output voltage ripple that helps to provide high quality power for industrial and consumer applications. It is used for controlling the voltage level for a variety of applications such as fans, pumps, light bulbs, lighting systems, vending machines, industrial tools, etc. It is also used in battery operated systems, where it maintains the output voltage and current levels while the load current changes. It also offers a wide input-voltage range, allowing the system to work in a variety of voltage supplies (various wall or vehicle supplies).

Working Principle

The L296PHT DC to DC switching regulator works based on the buck topology, producing the regulated output voltage through a converter circuit. The voltage converter circuit is composed of a pair of power MOSFETs (metal-oxide-semiconductor field-effect transistors) which together with a Built-in Power Diode (Buck topology), are responsible for converting a higher input voltage into a stable lower output voltage. As it uses MOSFETs, it is able to switch between the two states up to 4MHz. During the process, the buck converter significantly reduces the voltage drop on the input supply, providing high efficiency and stable output voltage levels. It has built-in protection features such as Under Voltage Lockout and Over-Temperature Protection for added safety.

The L296PHT offers a maximum current rating of 2A with a minimum on-time of 220ns, operating at a frequency range of 1kHz to 4MHz. In addition, it also offers adjustable output voltage with a nominal voltage of 5V and a voltage range of 4.5V to 36V that can be adjusted via an external timing source. The device is designed to have high efficiency, low noise, and fast transient response, which helps to provide efficient, reliable and stable power supply.

The L296PHT is an ideal solution for powering a variety of industrial and consumer electronic devices where high performance, low noise and reliable power output is required. It provides stable output voltage levels and is highly efficient, enabling the system to reduce power and noise waste. With its high switching frequency and easy to configure design, L296PHT provides a cost-effective solution for powering a variety of industrial, medical and consumer devices.
