The IP2002 is a switching regulator from Intersil Corporation which is used in many applications as a DC-DC converter for regulating voltage. It is also known as an integrated, two-phase switching regulator. The device consists of two buck regulators and two linear regulators in a single package, and can step up, step down, and invert the input voltage. It is used to regulate voltage in a wide range of applications, including medical, telecommunications, industrial, and automotive, to name a few.

The IP2002 features a wide input voltage range (3V to 20V) and operates at a maximum frequency of 2MHz. It also offers low quiescent current which is beneficial for battery powered applications. It has a precision reference voltage of 0.8V and provides a maximum output current of 4A. Its dual output configuration makes it suitable for many applications, including DC-DC converters, and power supplies for 12V, 24V, 36V, and 48V systems.

The IP2002 includes two buck regulators and two linear regulators. The buck regulators are used to boost or step down input voltages. They operate in parallel to provide higher output current and higher efficiency for applications that require more power. The two linear regulators are used to regulate the output voltage of the buck regulators. They feature a constant current limit and current fold-back, which are beneficial in applications where the load may vary significantly.

The IP2002 features low operating temperature, low noise, and a high operating alarm threshold. It also offers a protection circuit to protect against over-voltage and reverse polarity. The device also has an asynchronous switching output which provides a high noise immunity and a higher efficiency than synchronous switching.

The working principle of the IP2002 is simple. It monitors the input voltage and compares it to a reference voltage. If the input voltage is lower than the reference voltage, the converter increases the output voltage, and if it is higher, the output voltage is decreased. The IP2002 also adjusts the operating frequency of the converters to match the input voltage and load. This ensures the output voltage is regulated at the optimum level.

Overall, the IP2002 is an integrated, two-phase switching regulator specifically designed for use in DC-DC converter applications. It features a wide input voltage range, low quiescent current, and dual output configuration. It is also very efficient, with an operating temperature range of -40°C to 85°C, and a maximum operating frequency of 2MHz. These features make it suitable for use in a wide range of applications, and it can be used to regulate voltage in both 12V, 24V, 36V, and 48V systems.
