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.
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.
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.
PMP1941: 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.
PMP1941.4: A low cost TPS40200 buck converter produces a 5V @ 0.5A output. The input voltage is clamped to 30V max with the addition of a transient voltage-clamping circuit. A dithering circuit creates spread-spectrum operation on the switching frequency to lower EMI, making this circuit suitable for automotive use.
PMP30047: A quasi-resonant isolated flyback is employed to charge two lead-acid battery elements, starting from high-line mains. The converter accepts two external signals (referred to secondary side) to provide the reference voltages, which set output voltage and current. The converter shows good wide-range efficiency thanks to valley-switching modulation.
