Simple Synchronous Buck Converter Design - MCP1612
. The MCP1612 is designed to allow the use of ceramic,. The output voltage of the MCP1612 is easily set by the. tantalum or aluminum electrolytic capacitors as output. use of an external resistor divider network. The divided-. filter capacitors. The output capacitor is chosen to meet. down output voltage

adequate power supply decoupling. An. effective decoupling scheme consists of a 0.1 µF ceramic capacitor (high frequency bypass) in parallel. with a 4.7 µF tantalum capacitor for each amp of output current (low frequency bypass). This capacitor. scheme should be used for all supply voltages and should

Converting A 5.0V Supply Rail To A Regulated 3.0V
LDOs require the output. capacitor to be either tantalum or aluminum electrolytic. to produce a stable system. These capacitors have a. large Equivalent Series Resistance (ESR) when. compared to ceramic capacitors. Tantalum or. aluminum electrolytic capacitors are normally cheaper. than ceramic
