PMIC - Voltage Regulators - DC DC Switching Regulators
The S-8353A45MC-IRET2U (S-8353A45MCR for short) is a synchronous step-down switching regulator that can be used to power a variety of electronics from a wide input voltage range. It can produce an adjustable output voltage from 2.5V to 5.5V and features a constant on-time control circuitry. It is designed for easy implementation in space-constrained applications and offers high efficiency, as well as an enable/disable feature to conserve power when required.
Working Principle
S-8353A45MC-IRET2U works using a synchronous buck-boost topology. This topology is similar to the conventional buck topology, except that a fourth transistor is added to the circuit. This fourth transistor is a pass transistor, which allows the output voltage to be adjusted independently of the input voltage. By controlling the gate voltage of this transistor, the output voltage can be set to any value between the input voltage and ground.
The S-8353A45MC-IRET2U also includes an enable/disable control to conserve power when the output voltage is not needed. When the enable pin is connected to GND, the chip will automatically enter a low-power standby mode, which is significantly more power efficient than the normal operating mode.
Application Field
The S-8353A45MC-IRET2U is designed for applications that require a wide input voltage range with limited space. It is suited for systems where low voltage and high current levels are necessary and can be used to power a variety of different components. It can be used in a wide range of applications, such as powering LCD monitors, DSP microcontrollers, or embedded systems. It is also suitable for automotive and industrial applications that require robust power solutions.
The S-8353A45MC-IRET2U is an excellent choice for applications that need a high efficiency and adjustable output voltage. It is a versatile chip that can be used in a wide variety of applications and offers superior performance in a small footprint.
