Reducing noise on the output of a switching regulator
www.ti.comSnubber circuit A snubber circuit contains a resistor and capacitor that should dampen the switch-node ringing by absorbing the energy stored in the parasitic elements of the MOSFETs and printed circuit board (PCB). For more detail about designing a snubber circuit, see Reference 2. The test board used a 330-pF C SNUB and an 8.2-Ω R SNUB.
Topologies for switch mode power supplies
www.st.comthe circuit capacitance and the primary to secondary transformer leakage inductance. So, a single switch flyback nearly always requires a snubber circuit limiting this voltage spike (see figure 5). In a double switch flyback, the leakage inductance of the power transformer is much less critical (see figure 6). The two demagnetization diodes (D ...

static.sparkfun.comFlyback diode or snubber diode! Adding a diode in parallel with the motor provides a path for dissipation of stored energy when the switch is opened! +5V The flyback diode allows charge to dissipate without arcing across the switch, or without flowing back to ground through the +5V voltage supply. + –
Snubber Circuit for Buck Converter IC : Power Management
fscdn.rohm.comSnubber Circuit for Buck Converter IC In buck converter ICs, many high-frequency noises are generated at switch nodes. A snubber circuit provides one way of eliminating such harmonic noise. This application note explains how to set up the RC snubber circuits. RC snubber circuit Figure 1 shows the circuit of buck switching converter. In an
