The recommended operating voltage range for HEF4543BP,652 is 4.5V to 15.5V, with a typical voltage of 12V.
To ensure proper thermal management, provide a heat sink with a thermal resistance of less than 10°C/W, and maintain a maximum junction temperature of 150°C.
The maximum frequency of operation for HEF4543BP,652 is 100 kHz, but it can be operated at higher frequencies with reduced output current.
Yes, HEF4543BP,652 is suitable for switching power supply applications due to its high current capability and fast switching times.
Use a voltage regulator or overvoltage protection circuit to prevent voltage exceeding 15.5V, and add current limiting resistors or fuses to prevent excessive current.
