Automotive grade 3.3 - 5V Transformer Driver for Isolated Power Supplies - SCM1212BTA-Q

A newly released SCM1212BTA-Q of push-pull power primary side controller from MORNSUN is special for automotive applications. It complies with AEC-Q100 standards and is produced in facilities certified to IATF16949, and accepts a wide input voltage range of 2.7 - 5.5V that is compatible with 3.3V/5V input. 

Its maximum power is up to 3W, and will not be damaged under the impact of high input voltage of 9V for 1S. The driving symmetry of the power MOS inside the chip is high, thereby reducing the bias degree of the push-pull topology, making it a reliable solution for isolated power supply for CAN, RS485, RS232, and on-board system of Controller LAN.

Power solution

CTTF0505-1T transformer, with a packaging size of 12.50 x 8.70 x 5.90mm, is specially designed for use with IC. It is mainly used for electrical isolation scenario that requires 5VDC input and 5VDC output with power less than 1W, such as digital circuit, analog acquisition circuit, and data exchange circuit. It can be used with our IC SCM1212BTA-Q for design.
