The ICE3BS02 is a low cost and low power offline switcher integrated circuit (IC) which is typically used in basic AC/DC power conversion applications. It is designed to fit into small packages, thereby making it suitable for use in space-constraint applications. The ICE3BS02 combines both active and passive components, and works as an AC-DC, DC-DC, or DC-AC converter. This device is beneficial in a range of automotive, industrial, medical, and household and consumer applications.

The ICE3BS02 employs a Semi-Resonant Zero Current Switching (SRZCS) topology. This topology combines elements of both resonant and discontinuous conduction modes, thereby offering higher efficiency and better performance than standard discontinuous conduction mode (DCM) controllers. This leads to reduced power losses, improved EMI performance, reduced component count and smaller system size. The SRZCSTM technology results in a high efficiency power conversion system and is beneficial in the development of low cost and high performance power solution.

The ICE3BS02 integrates several components i.e., a high voltage start-up regulator (HVSU), an oscillator, an error amplifier (EA), a PWM controller and a power MOSFET driver. It also features an optimal VCCstart up regulator circuit that helps improve start-up stability and reduce component count.

The ICE3BS02 is a fully-integrated architecture which features an adjustable external current sense resistor. This allows monitoring of the current in the power converter. It also features an adjustable limit voltage that eliminates the need for an additional voltage limiter. This further reduces component count and the overall system cost.

The ICE3BS02 also features an adjustable frequency control pin that allows independent selection of the PWM controller frequency. This can significantly reduce the component count and improves the current performance of the system. The ICE3BS02 also offers a built-in protection from up to three different fault conditions. This includes over load, short-circuit, over voltage, and over current.

The ICE3BS02 is a very versatile device which provides higher performance and better efficiency compared to most of the existing power solutions. It is ideal for use in a variety of AC-DC, DC-DC, and DC-AC converters. It is suitable for applications in automotive, industrial, medical, and home and consumer electronic appliances.
