  • Synchronous converter
    Patent number: 10622894
    Abstract: A synchronous converter for driving a load (4) comprises a first switch (M1) coupled in series with a second switch (M2) via a node (x), an inductor (L1) coupled to the node (x), input terminals (10, 11) for receiving an input voltage (Vin) from a power source, output terminals (12, 13) for supplying an output current and an output voltage to the load (4), a first mode wherein the first switch (M1) is in an on state and the second switch (M2) is in an off state, and wherein the first switch and the inductor (L1) form a series arrangement coupled between the input terminals (10, 11), a second mode wherein the first switch (M1) is in the off state and the second switch (M2) is in the on state, and wherein the second switch (M2) and the inductor (L1) form a series arrangement coupled between the output terminals (12, 13).
