The utility model refers to the equipment of measuring instruments and systems, radar equipment and microwave electronics. The miniature DC / DC power module contains an integrated PWM controller chip, to the input of which a choke L1 and a capacitor C1 are connected. A bootstrap capacitor C3, also connected to the bootstrap circuit of the integrated circuit, and a reactor L2, to which the capacitor C2 is connected, are connected to the output of the integrated microcircuit. Also capacitors C1 and C2 are connected to the grounded common point of the power circuit of the integrated microcircuit. The capacitor C4 is connected to the power supply terminal of the integrated microcircuit. Resistors R1 and R2 of the first resistive divider are connected to the feedback circuit of the integrated microcircuit, while the resistor R1 is connected to the output circuit of the module voltage. The capacitor C5 and the terminals of resistors R3 and R4 of the second resistive divider are connected to the resolution and clock synchronization circuit of the converter IC. Resistor R3 is connected to the input of the integrated circuit. Resistors R2, R4 and capacitor C4 are connected to the grounded common point of the analog circuit of the integrated circuit. The technical result is a reduction of induced interference to the input-output of the converter and to the control circuits of the microcircuit. 1 z.s. f-ly, 3 ill.
