S-8358B40MC-NQZT2G Application Field and Working Principle

S-8358B40MC-NQZT2G is a DC-DC switching controller from Supertex, a brand recognized for its high-performance, reliable and cost-effective power devices. This DC-DC switching controller is designed specifically for cost-sensitive and energy-efficient system applications.

The S-8358B40MC-NQZT2G is a PMIC (Power Management Integrated Circuit) which fall into the Voltage Regulators and the DC-DC Switching Controllers family. The device is composed of three parts – the gate driver, PWM control and the external power MOSFET – which can be used to create a DC-DC buck switching converter. The device produces an 8V output voltage at a maximum current of 1A from an input voltage of up to 24V.

In terms of functionality, the device features a wide range of features, including over-voltage protection, under-voltage lockout, short-circuit protection, over-temperature protection and a load disconnect fault mode. Additionally, the device includes soft-start, which increases the output voltage gradually instead of instantly when the load is applied.

In terms of working principle, S-8358B40MC-NQZT2G works in the following way: It features an internal oscillator circuit which produces a fixed frequency, switching cycle. The output of the oscillator is used as a control signal to drive the MOSFET gate, which when turned on acts as a switch, allowing the current to flow through the circuit. The oscillator frequency of the device can be adjusted by varying the external resistance connected to the device. When the frequency is varied, the duty cycle of the cycle is switched, thus changing the voltage output of the device.

In terms of applications, S-8358B40MC-NQZT2G can be used in a wide range of applications like automotive, consumer and industrial applications. The device provides a reliable and cost-effective solution for such applications as LCD TVs, lighting control, alternative energy systems, LED lighting, data storage equipment, and many other consumer and industrial applications.

In conclusion, S-8358B40MC-NQZT2G is a DC-DC switching controller from Supertex, featuring an 8V output voltage at a maximum current of 1A from an input voltage of up to 24V. This device includes a wide range of features, including over-voltage protection, under-voltage lockout, short-circuit protection, over-temperature protection and a load disconnect fault mode. It has a wide range of applications, making it a reliable and cost-effective solution for a variety of consumer and industrial applications.
