Flyback, Buck for Automotive (52V @ 0.04A)
PMP1941.2: A triple-output non-isolated flyback converter provides a regulated low voltage and two high voltage rails. A buck converter with an input transient voltage-clamping circuit produces a 5V rail. The addition of a dithering circuit creates spread-spectrum operation on the switching frequency to lower EMI, making this circuit suitable for automotive use.
Flyback, Buck for Automotive (4.5V @ 0.05A)
PMP1941.5: A TPS70501 linear regulator supplies a 4.5V output in parallel with the 5V rail. This provides a low current backup voltage when the the buck converter is disabled.
Flyback, Buck for Automotive (3.7V @ 0.5A)
PMP1941.3: A triple-output non-isolated flyback converter provides a regulated low voltage and two high voltage rails. A buck converter with an input transient voltage-clamping circuit produces a 5V rail. The addition of a dithering circuit creates spread-spectrum operation on the switching frequency to lower EMI, making this circuit suitable for automotive use.
PMP11769 700W Automotive External Audio Amplifier Reference Design | TI.com
PMP11769: The PMP11769 reference design is a complete solution for a 700W automotive external amp. The boost converter provides 36.0V @ 10.0A continuous / 20.0A peak from an input voltage of 9-16V. It contains two premium Class-D audio amplifiers, which provide 2x 175W @ 4-Ω load (left & right channel) and 1x 350W @ 2-Ω (subwoofer).The design is well suited for car audio external amp applications due to its thin profile and high power output.
