PMIC - AC DC Converters, Offline Switchers

PMIC, or power management IC, are integrated circuits that power, control, and monitor batteries or other remote power source. They are used for a variety of applications including automobiles, computers, medical equipment, and consumer electronics. One of the most common PMICs available today is NCV1351BPG.The NCV1351BPG is a power management unit designed for use in offline switched-mode power supplies (SMPS) commonly found in home and office appliances. It is a single-channel, synchronous, step-down converter that can provide up to 200mA of output current. The NCV1351BPG is offered in a space-saving 4x4mm leadless QFN package.The NCV1351BPG integrates several features including a high-frequency toggle switch, over-current protection, under-voltage protection, adjustable switching frequency, and adjustable soft-start. The switching frequency range is from 1MHz to 6MHz, giving the system designer flexibility in optimizing the board layout. The device also incorporates a voltage feedback system that allows for accurate output regulation.The NCV1351BPG features an adaptive on-time control topology, which allows it to efficiently handle a wide range of loads. It is also optimized for low-noise operation and can operate with a wide input voltage range (4V–32V).In terms of its application field, the NCV1351BPG can be used to power a variety of home and office appliances, such as DVD players, personal computers, routers, and gaming consoles. Thanks to its power saving design and wide input voltage range, it can also be used in European and North American products, as well as any other region.At its core, the NCV1351BPG works by continuously regulating the switch\'s on-time. The on-time is regulated so that it is proportional to the load current, which allows it to maintain an accurate output voltage, even under changing load conditions.The NCV1351BPG also utilizes an oscillator to regulate the switching frequency and the soft-start time distribution. The oscillator is based on the SOT-23-5 package. The device\'s over-current protection feature is triggered when the current passing through the inductor exceeds the threshold set by the system designer. The device also utilizes an under-voltage protection feature to protect it from input voltage drops.Overall, NCV1351BPG is a reliable, efficient, and cost-effective power management solution for home and office appliances. It allows the system engineer to easily achieve tight output voltage regulation and improved system efficiency. In addition, it is offered in a space-saving 4x4mm leadless QFN package, making it ideal for modern, space-constrained designs.
