Power Management Integrated Circuit (PMIC) are increasingly becoming an important component in modern electronic systems. As the name suggests, PMIC’s are integrated circuits designed to manage the power supply of a system. PMICs come in a variety of different forms, each with its own particular applications and range of features. PMIC\'s can be divided into two main categories, AC DC Converters and Offline Switchers.

NCP12700BMTTXG AC DC Converters

The NCP12700BMTTXG AC DC Converters are designed for high-efficiency, low-noise power conversion of AC power sources. The NCP12700BMTTXG AC DC Converters utilize a zero voltage switching topology to minimize switching losses and reduce noise. The NCP12700BMTTXG AC DC Converters are also capable of generating multiple outputs with various levels of regulation, making them perfect for applications that require multiple outputs with different levels of regulation.

The NCP12700BMTTXG AC DC Converters feature a wide input voltage range of between 150VAC and 230VAC. The device has a wide output range, with a maximum of 2.6A at 24V. The NCP12700BMTTXG AC DC Converters come with an adjustable frequency of up to 500kHz. The device has a peak efficiency of over 90%. The NCP12700BMTTXG AC DC Converters also feature a number of protection features, including overvoltage, short-circuit, over-temperature, external sense, and open loop protection.

NCP12700BMTTXG Working Principle

The NCP12700BMTTXG AC DC Converters utilize a zero voltage switching topology to minimize switching losses. The device is composed of a bridge rectifier and a switching MOSFET, connected in series. When the AC input voltage is higher than the output voltage, the power switch is fired, allowing current flow and energy transfer from the AC source to the output. As the voltage drops, the power switch is disabled and the power transfer stops. This process is repeated when the AC voltage rises again.

The NCP12700BMTTXG AC DC Converters feature a range of protections, including overvoltage protection (OVP), over-temperature protection (OTP), short-circuit protection (SCP), external sense, and open loop protection. The OVP prevents any damage to the converter by shutting it off when the output voltage exceeds a predetermined limit. Similarly, the OTP protects the device from overheating by automatically shutting off the converter when the temperature rises above a certain threshold. The SCP works by detecting when the current is too high on the output and turns off the power switch to protect the unit from damage.

The NCP12700BMTTXG AC DC Converters also feature an external sense protection feature, which allows for current sharing between multiple outputs. By sensing the voltage drop across an external resistor and using it to adjust the output voltage, current sharing can be enabled. This protects the system by ensuring that the current drawn by one output does not cause an overload on the other outputs. The open loop protection feature is also present, which monitors the output voltage and automatically adjusts it when it exceeds a certain threshold. This helps to ensure that the output is regulated and keeps the converter from becoming overloaded.
