This 22-36v input to 12V 3A power supply circuit using LTM8025 is designed using LTM8025 step down μModule converter which included in one package: switching controller, power switches, inductor and all support components.
LTM8025 step down μModule converter operate on a wide range input voltage of 3.6V to 36V and supports an output voltage range of 0.8V to 24Vand a switching frequency range of 200kHz to 2.4MHz, each set by a single resistor. To finish the design of the circuit only the bulk input and output filter capacitors are needed .
This 3.3V from 5V power supply circuit is designed using ADP2118 dc converter designed by Analog Devices ad is an synchronous, step-down, dc-to-dc converter.
