PMIC (power management integrated circuit) is a range of integrated circuits that are used for managing various power management functions, such as voltage regulators, DC-DC switching regulators, power converters, and other related functions.

CS51413GD8 is one such example of a voltage regulator. It is designed for low-cost point-of-load supply regulation applications, such as notebook and tablet computers, TV set top boxes, and other small appliances. The voltage regulator supports up to 12V input and can provide up to 36V output.

Application Field

Due to its low-cost, low-thermal-gradient, low-noise characteristics, CS51413GD8 is an ideal voltage regulator for consumer electronics applications, including:

• Notebook computers
• Tablet PCs
• Set-top boxes
• Digital TV boxes
• Cellular phones
• 3D printers
• Laptops

The voltage regulator is also suitable for industrial applications such as:

• Industrial automation
• Test and measurement
• Medical equipment
• Lighting systems
• Robotics

Working Principle

The CS51413GD8 voltage regulator works on the principle of pulse-width modulation (PWM) to regulate the output voltage. Essentially, an output signal is generated that controls the switching of a power switch, which regulates the voltage level of the output signal.

In the case of the CS51413GD8, the output voltage is adjustable from 0.5V to 12V, with a step resolution of 12mV, and a voltage accuracy of ±2%. The switching frequency is adjustable from 500kHz to 2MHz, and the minimum operating voltage is 0.8V.

The CS51413GD8 also includes several safety features such as an over-current protection, under-voltage lockout, and an over-temperature protection to prevent damage to the device or other components in the system.

The device also includes several integrated components such as voltage and current sense resistors, an adjustable divider to set the output Voltage, an over-temperature protection, and a discharge resistor to reduce inrush current.

The CS51413GD8 voltage regulator is designed for high efficiency and performance, with efficiencies of up to 95%. The device also has low power dissipation and low operating current, making it ideal for energy efficient and portable applications.
