CS51414EDR8G is a highly efficient, low-voltage DC-DC switching regulator that is designed to meet the needs of space-constrained, ultra-low voltage applications. This switching regulator is capable of delivering a wide range of output voltages, with the highest output current up to 2A, to various portable consumer technologies such as laptops, consumer electronics, and handheld devices. This regulator is also available in a variety of formats to suit the specific needs of any application.

CS51414EDR8G belongs to PMIC (Power Management IC) family of devices and is also classified as Voltage Regulators, meeting the need for many high efficiency DC DC switching regulator applications. The high efficiency and robust design allows it to be used in a variety of consumer electronics, automotive and industrial environments. The device features a maximum output current of up to 2A, a maximum throughput of up to 30 Mhz, and wide input voltage range of 0.8V to 20V.

The CS51414EDR8G works on the principle of pulse wave modulation, which is a type of pulse width modulation. In this technique, the output voltage is controlled by adjusting the duty cycle and width of the pulses. The input voltage is applied to the circuit and is compared to a reference voltage. Whenever the input voltage is higher than the reference voltage, the circuit triggers a pulse switch, which connects the input voltage to the switching capacitor. This capacitor is then discharged and the voltage drops. Once the voltage drops below the reference voltage, the pulse switch turns off, allowing the switching capacitor to recharge.

The CS51414EDR8G provides various modes of operation, including Constant Voltage Regulation, Constant Current Regulation, and Voltage Tracking. These modes allow the user to customize the output voltage and current to meet the requirements of different applications. For example, Constant Voltage Regulation is used to maintain the output voltage as close to the voltage set-point as possible, even during load variations. On the other hand, Constant Current Regulation is used to regulate current flow and maintain a consistent voltage. Lastly, the Voltage Tracking mode maintains the output voltage as closely as possible to the input voltage.

The CS51414EDR8G supports a wide variety of packages such as WLCSP (Wafer Level Chip Scale Package), QFN (Quad Flat NoLead) and MLCP (Multi-Leaded Chip Scale Package), making it suitable for a wide range of applications, ranging from consumer electronics to automotive systems. It also features adjustable frequency and fast start up time, 3-input limit protection, and thermal shutdown circuit for protection against over-temperature conditions.

The CS51414EDR8G is widely used in consumer electronics devices such as tablets, laptops, digital cameras and GPS, and also in automotive systems, medical devices, and industrial control systems. It is ideal for low-voltage applications that require high-efficiency power conversion and are space-constrained.
