Cheap PWM IC Makes Synchronous Gate Driver: 02/04/99 EDN-Design Ideas / (added 10/06) A system with a µP,
memory, and peripherals usually requires several power-supply voltages. Designers typically use local switching regulators to produce the desired voltage rails. One of the most common
topologies, the synchronous buck regulator, converts a 5 or 12V bus to some other, lower voltage.... |

Circuit reduces negative Voltage stresses on Control IC: 04/18/02 EDN Design Ideas / (added 1/05) In a
synchronous, buck switching power supply, the two FETS and the output inductor meet at the phase node (Figure 1). The phase node often connects directly to the control IC. The voltage on this
node swings from the input voltage to some voltage lower than ground. If the voltage goes too far below ground, the ESD structures or other circuitry within the control IC can become
forward-bia... ... |

Controlling Slew Times Tames EMI in Offline Supplies: 11/14/02 EDN Design Ideas / (added 1/05) EMI from
offline switching power supplies typically causes all sorts of problems for power-supply designers. You may need a large EMI filter to meet FCC emission requirements. Switchers for high
efficiency produce high-frequency switching noise that can propagate through the rest of the system and cause problems.... |

Interference Free Switch Mode Pre-Regulator: Designed by Andrew R. Morris I created this circuit to fix an overheating
problem with a small Chinese-made stereo set. This simple solution to a perplexing problem worked so well that I felt the need to share it. This circuit can be used for other applications as
well (circuit added 6/07) |
