Description
Technical Field
The invention belongs to the technical field of integrated circuits, and particularly relates to a BUCK _ DC-DC BUCK converter.
Background
With the rapid development of new energy automobiles, 5G communication and data centers, the requirements for high-voltage input, high conversion ratio and high-power density switching power supplies, such as 12V, 24V and even 48V high-voltage input, are greatly promoted; on the other hand, with the continuous progress of semiconductor manufacturing processes, the load power supply voltage has been reduced to 1V or even below; high BUCK ratio BUCK power converters are particularly important to bridge the large voltage difference between the input power rail and the termination module.
The traditional half-bridge BUCK _ DC-DC has wide application because the topology is simple and easy to control, and brings direct benefits in the aspects of efficiency, switching frequency and cost; however, when the input voltage is much larger than the output voltage, the advantages of the conventional half-bridge structure are rapidly reduced; first, to achieve a large switching ratio, the turn-on time of the half-bridge BUCK-DC BUCK converter must be greatly reduced, which is determined by the ratio of the output voltage to the input voltage, and to achieve such a short turn-on time, the drive time of the feedback control loop and the power transistor must be correspondingly reduced. On the other hand, to accommodate rising input voltages, larger power switches must be used to withstand higher device withstand voltages, which necessarily results in longer drive delays. Secondly, for a high step-down ratio, the low-side power switch of the half-bridge buck converter is in a conducting state most of the time in each switching cycle, and the conduction loss of the low-side power switch is also increased remarkably, so that the size of the low-side power switch is inevitably far larger than that of the high-side power switch, the switching loss of the low-side power switch is greatly increased, and the balance among grid driving, dead zone control and switching noise control is more complex. However, in the half-bridge BUCK _ DC-DC BUCK converter, when the power supply inputs the voltage V IN Much higher than the output voltage V OUT These benefits can quickly diminish. First, to achieve a large voltage conversion ratio, the high-side power switch on-time t of the half-bridge BUCK _ DC-DC BUCK converter must be greatly reduced, which is in contrast to V OUT /V IN Is linearly proportional. To achieve short on-times, the propagation delay caused by the power transistor, gate driver, feedback control loop must be reduced accordingly. On the other hand, however, to accommodate rising V IN Larger power transistors must be used to maintain a high breakdown voltage, which results in longer delays. Second, for the data from V OUT /V IN High of definitionThe BUCK ratio, the low side power switch of the half-bridge BUCK-DC BUCK converter, is turned on most of each switching cycle, significantly increasing its conduction losses. Therefore, its size must be much larger than the high-voltage side, resulting in a large increase in switching loss, further complicating the design tradeoff between gate drive, dead-band control, and switching noise control. Finally, high switching frequencies help to reduce the size of power passive devices, in particular inductors, and thus achieve higher power densities, however, as the switching frequency is further increased, the switching losses are also significantly increased, while placing higher demands on internal control delays and drive.

Wherein:
