600V Ballast Controller IC with Adaptive Zero-Voltage Switching, Internal Crest Factor Over-Current Protection and an Integrated Bootstrap Diode in a 8-Pin Dip package.; Similar to IR2520D with Lead Free Packaging
The maximum operating temperature range for the IR2520DPBF is -40°C to 150°C, with a junction temperature of up to 175°C.
Proper cooling can be achieved by using a heat sink with a thermal resistance of less than 1°C/W, and ensuring good airflow around the device. The heat sink should be attached using a thermal interface material with a thermal conductivity of at least 1 W/m-K.
The recommended gate drive voltage for the IR2520DPBF is between 10V and 15V, with a maximum gate-source voltage of ±20V.
Overvoltage protection can be achieved using a voltage clamp or a zener diode, while overcurrent protection can be achieved using a current sense resistor and a comparator or a dedicated overcurrent protection IC.
The maximum switching frequency for the IR2520DPBF is 500 kHz, but it can be operated at higher frequencies with proper design and layout considerations.
