Isolation DCDC-CN3501

The CN3501TER is a push-pull transformer driver specially designed for small size, low standby power consumption micropower isolated power supply, which can realize 5V-5V, 12V-5V isolated power supply with output power of 1~2W by matching the simple input/output filter capacitors, isolation transformer and rectifier circuits peripherally. The CN3501TER chip has an integrated oscillator to provide a pair of high-precision complementary signals to drive two N-channel MOSFET, which is designed according to the symmetrical structure of the chip to ensure the high symmetry of the two power MOSFET and avoid the bias magnetization of the circuit in the process of operation. A high-precision deadband control circuit is designed inside the chip to ensure that no commutation occurs under various operating conditions.
