The TPS54620 is a synchronous, step-down, dc-dc converter with integrated high- and low-side FETs. It is rated for a continuous output of 6 A. In order to increase the output current capability, it is possible to operate two TPS54620 circuits in parallel. Certain techniques are required in the design to ensure that each of the TPS54620 converters provides an equal share of the output current.

A buck DC/DC switching converter has a minimum on-time at which it can operate. This limits theminimum output voltage a converter can regulate to while keeping a fixed frequency. The limitation of theminimum on-time is often only considered for the steady-state output voltage; however, when the outputvoltage ramps up, in most cases the output voltage ramps up from 0 V.

This application report offers a tutorial discussion on jitter in switching DC-DC converters. Not all power supply designs are equally susceptible to jitter, nor are they equally affected by jitter. Modes of switching jitter are defined and explained for several popular control architectures, which are then analyzed for sources of jitter. An example contrasting the amount of jitter and effect on o - Calculating EfficiencyPDF, 175 Kb, Archivo publicado: feb 19, 2010

One of the well-known benefits of current-mode control is that the system stability can be easily achieved by Type II compensation design. It is possible to improve the transient response of a current mode DC/DC converter by adopting Type III compensation to boost the crossover frequency and phase margin. Type III compensation is simple to design and needs only one extra component. - Demystifying Type II and Type III Compensators Using Op-Amp and OTA for DC/DC CoPDF, 782 Kb, Archivo publicado: jul 11, 2014

Power dissipation performance must be well understood prior to integrating devices on a printed-circuit board (PCB) to ensure that any given device is operated within its defined temperature limits. When a device is running, it consumes electrical energy that is transformed into heat. Most of the heat is typically generated by switching devices like MOSFETs, ICs, etc. This application report discu
