The device also provides over-current, short-circuit, and over-temperature protection, making it a very reliable power source despite its small cost.

Technical Specifications

The CS8361YDWFR16G is a step-down voltage regulator, with a wide range of input voltage from 5V to 18V. It has an adjustable output voltage from 1V to 18V, and can provide up to 500mA of output current. The device also features programmable shutdown, standby and low-quiescent current modes. The shutdown mode can reduce current consumption down to 0.3uA, while the standby mode can reduce current consumption to 100nA (typical).

The device also features very low output ripple, allowing designers to create efficient and reliable power supplies. For example, the maximum output ripple for a 12v output is 0.6mV (typical). Other features included are over-current, short-circuit and over-temperature protection, making it suitable for all types of applications.

Working Principle

The CS8361YDWFR16G is a step-down voltage regulator, which works by taking a higher voltage from the input, and then reducing it to a lower voltage at the output. It does this by using a MOSFET switch, which is turned on and off by the internal control unit. The internal control unit is what determines the voltage of the output. It is able to do this accurately, because of the high accuracy of the internal reference voltage.

When the input voltage rises above the desired output voltage, the internal control unit turns on the MOSFET switch, connecting the input to the output. This allows current to flow from the input to the output and reduces the voltage to the desired level. When the input voltage drops below the output voltage, the switch is turned off and the device is in standby or sleep mode, until the input voltage rises again.

The CS8361YDWFR16G regulator can also be programmed to switch between different modes, such as shutdown, standby and low-quiescent current modes. This allows the user to choose the most appropriate solution for their application, based on their power consumption needs. The device also offers over-current, short-circuit and over-temperature protection, making it suitable for all types of applications.
