PMIC - AC DC Converters, Offline Switchers

The ICE3AR2280CJZXKLA1 is a robust, integrated buck active clamp controller with various power level settings and is used in a wide range of AC/DC converter and offline switcher applications. The controller is used in off-line applications that require an optimized efficiency while still keeping a wide input voltage range, comprehensive system protection and high reliability with an integrated soft start feature. Additionally, the controller complies with no load power consumption regulations.

The ICE3AR2280CJZXKLA1 works by using its advanced active clamp switching control to absorb and clamp the voltage surge (flyback voltage) generated every time the switcher circuit is operated. During normal operation, the controller holds the clamp voltage to a constant level by either providing positive drive to the upper switch or by driving the lower switch to ground until the clamp voltage is reached. This active clamp mechanism results in better efficiency, increased overall component count, a scalable power rating and eliminates the need for additional external components.

In addition, the ICE3AR2280CJZXKLA1 features a 2.0A Gate Driver Output, low start-up current spike, built-in current limiting protection and auto-restart protection under over current conditions. This device also supports a wide input voltage range up to 775V and is available in both standard and enhanced variants.

The ICE3AR2280CJZXKLA1 provides an optimal power solution for various types of applications, such as radio-frequency (RF) amplifiers, AC/DC converters, point-of-load converters, automotive and industrial control circuits. The inherent soft-start feature ensures the device is able to maintain optimal overall efficiency while limiting the start-up current spike. In addition, the controller offers a wide adjustable range of switch frequency from 1kHz up to 500kHz, allowing for additional flexibility in design.

In summary, the ICE3AR2280CJZXKLA1 is an efficient, reliable and robust AC/DC and offline switcher power solution for a variety of applications. The integrated active clamp control offers a wide input voltage range up to 775V, improved efficiency, and optimum system protection. The device also features numerous additional features such as 2.0A Maximized Gate Driver Output, low start-up current surge, built-in static current-limiting out protection and auto-restart protection under over current conditions. Combined, these features make the ICE3AR2280CJZXKLA1 the ideal choice for high efficiency and reliable system designs.
