The MP1580HS-LF’s working principle relies on DC-DC conversion. The input voltage is stepped down by a voltage regulator integrated into the device, enabling power to be supplied to the output with improved efficiency at a constant voltage level. The MP1580HS-LF uses a Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) control loop which regulates the ratio of output voltage by controlling the on and off periods of the switching transistor. The output voltage level can be set via external voltage divider and feedback components. The PWM control loop is active for light loads, where it maintains the desired output voltage within a fixed range, while the PFM control loop is active for heavy loads, where it ensures that the load current is not exceeded. A low inductance output capacitor is required to minimize the output voltage ripple and noise.
