Working Principle

The SRAH-03E1000 DC DC Converter uses a synchronous buck converter switch topology, which works in the following manner:

• The power switch is actuated, causing a current to flow from the source, through the power switch, to the output.The current is then fed to a pulse-width modulator (PWM) comparator.
• The PWM comparator compares the reference voltage applied to the output with the actual voltage measured at the output.
• If the voltage exceeds the set level, the PWM comparator signals the driver circuit to reduce the current until the output voltage is within the appropriate range.
• The output voltage will then remain at a consistent and accurate level.
