  • Minimizing Output Ripple During Startup
    PDF, 675 Kb, File published: Jun 22, 2017
    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. When the converter tri
  • Not All Jitter Is Created Equal (Rev. A)
    PDF, 555 Kb, Revision: A, File published: Jul 4, 2015
    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

  • TPS54620 Parallel Operation
    PDF, 412 Kb, File published: Mar 3, 2010
    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. T
  • Understanding Thermal Dissipation and Design of a Heatsink
    PDF, 59 Kb, File published: May 4, 2011
    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

  • Designing Type III Compensation for Current Mode Step-Down Converters (Rev. A)
    PDF, 298 Kb, Revision: A, File published: Sep 15, 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.
