AN1332 Power Supply Op Amps Circuits MCP6H01 R1 VOUT R2 R1* RSEN ISEN RSEN << R1, R2 circuit. which in turn controls the power supply DC output voltage. impossible to distinguish from change in current flow caused by the AC power supply. 6Hz 3mV sine wave and measure with a scope at the output test point. Power is defined as (Voltage)*(Current) the current within this equation comes in two flavors AC and DC. In other words, field.
