TIDA-01344: The TIDA-01344 reference design is a 24W, automotive 48V battery front-end power supply that generates 12V from a wide input range of 10V to 80V DC, up to 100V transient for LV148 standard compliance. The system consists of EMI filters for CISPR 25 compliance and circuit protection for clamping high voltage transients to safe levels for downstream circuitry. The fly-back controller implements primary side regulation with no optocoupler, allowing for extended life time and smaller board design, and the fly-back transformer is designed and qualified as automotive AEC-Q200 Grade 1.
PMP20128: This 6.5V @ 2.5A SEPIC converter is designed to operate over a very wide input voltage range. After initial power up at 6V input, the converter can operate down to 4.5V input by implementing a voltage doubler for to provide bias power. It requires minimal component count, a small PCB area and offers very good efficiency.
