REC3-0509SRW/H/B/M/SMD-R Working Principle

The REC3-0509SRW/H/B/M/SMD-R is a synchronous buck topology DC-DC converter that uses a MOSFET switch in its main circuit. The switch is driven by a comparison circuit which is generated using an internal oscillator. The duty cycle of the switch is determined by the input voltage, and this in turn determines the output voltage.

The device has integrated compensation voltage control that allows it to maintain a constant output voltage over a wide range of input voltage. A reference voltage of 1.24V is generated internally to allow for precise control of the output voltage. The reference voltage is passed through a voltage divider connected to the input of the power stage to create the reference voltage for the power stage.

When the input voltage is above the switching threshold of the switch, the comparison circuit drives the switch into an ON state. The power stage then takes over, pushing current through the load and regulating the output voltage to match the reference voltage. When the input voltage is below the threshold, the switch is driven into a OFF state and the output voltage falls to 0V.

The REC3-0509SRW/H/B/M/SMD-R features integrated safety protection features such as under voltage lock-outs, over voltage protection and thermal protection. These features ensure that the device operates safely even in cases of extreme input conditions. The device also has an integrated soft-start function that helps to reduce inrush current at start-up.

The REC3-0509SRW/H/B/M/SMD-R is an ideal choice for applications that require high efficiency, low cost and high reliability. It is also highly suitable for applications where a wide input voltage range is required. Its small footprint and high efficiency make it one of the most popular DC-DC converters on the market.
