Synchronous Buck circuit produces negative Voltage - 03/06/03 EDN-Design Ideas:
Many electronic systems require both positive and negative voltages to operate
properly. Generating an efficient, low-voltage positive output from a higher voltage
input typically entails the use of a synchronous buck regulator. But when generating a
negative output voltage from a positive input voltage, you'd typically use a flyback
topology, especially at higher output currents.....(design idea added 1/05) |

Synchronous Buck Reference Design - This reference design is a 5Vdc input to 1.65V
@ 1A output synchronous buck converter. The controller is the TPS40003 operating at
600KHz. The controller features Predictive Gate Drive, which minimizes the bottom FET
body diode conduction time. This provides the benefit of increased efficiency when
compared to a standard gate drive method....(added 3/05) |

Synchronous Flyback Circuit Provides High Efficiency Conversion - 07/22/04 EDN-Design
Ideas: Buck regulators are usually the first choice when you design nonisolated
step-down regulators unless the ratio of VIN to VOUT is greater than 10, the input
voltage is high, or both. Low duty cycle can be problematic for FET drivers and cause
current-mode control loops to lose control. Efficiency can fall
dramatically.....(design idea added 1/05) |

Synchronous OCM Buck-Boost - This reference design is synchronous buck-boost
converter that can deliver up to 3.8 A of continuous current at -5 V from a 5 V input.
This topology uses a synchronous buck controller (TPS5103) referenced to the negative
output rail. The synchronous MOSFETs allow this design to achieve a peak efficiency of
88%..... (added 3/05) |
