ICE3A1565FKLA1 – also known as "ECONO IC" – is designed to offer insulated gate bipolar transistors (IGBTs) with low losses and easy applications, without the need for external circuitry for programmability. This IC offers protection features against overvoltage and overcurrent, providing safety to the application. It has a wide voltage range up to 500V, allowing it to be used in a variety of applications.

The full integration of ICE3A1565FKLA1 offers a straightforward design and requires a minimum number of external components, making it very versatile and easy to use. The main features include programmable system timing and frequency, thermal protection, and IGBT protection from overvoltage or overload. Additionally, it provides low jitter electronics for precise frequency control.

The main application of ICE3A1565FKLA1 is for offline flyback topology DC-DC converters operating at high voltage up to 500V. These topologies are used in applications such as LED lighting, digital power supplies, rectifiers, low power DC-DC converters, and other use cases that require a low voltage, high frequency switching power supply. The ICE3A1565FKLA1 is a low-cost IC which enables designers to easily create low-power converters with excellent power conversion efficiency.

The working principle of ICE3A1565FKLA1 is based on the principle of resonant switching, where power is switched synchronously at the resonance frequency of an inductor/capacitor (LC) pair. By adjusting the time delay of the switch, it is possible to optimize the operating frequency, thus providing precise control of the converter. This control also increases efficiency and reduces losses from the power stage, allowing the IC to deliver high efficiency without the need for external components.

The IC also offers an easily configurable on/off current limit feature, protecting the IC from overcurrent. The system features an OVP (overvoltage protection) circuit, allowing it to be enabled only when the secondary output voltage is greater than the set value. Additionally, the IC provides a "hiccup" mode which can be used to create a dependable shutdown in case of an overload condition.

Overall, ICE3A1565FKLA1 is a versatile and cost-effective IC for creating offline flyback converters operating up to 500V. It offers a wide range of features, and its integrated components allow it to offer high efficiency and low power losses.
