Working Principle

The LM2599SX-ADJ/NOPB is a step-down (buck) DC/DC switching voltage regulator. It uses a power switch to convert an input voltage to an output voltage. The switch is driven by a control circuit that monitors the output voltage and adjusts the duration of each step to regulate the output voltage.The LM2599SX-ADJ/NOPB is configured to use fixed frequency pulse width modulation (PWM) for regulation of the output voltage. In this mode, the control circuit monitors the output voltage, and adjusts the duty cycle of the pulses to regulate the output voltage. The maximum switching frequency is 1.5MHz, which can be adjusted to lower frequencies for quieter operation.When the output voltage is lower than the desired setting, the control circuit increases the duty cycle and increases the output voltage, conversely, when the output voltage is higher than desired the control circuit reduces the duty cycle and the output voltage. This process continues at the set frequency to stabilize the output voltage and maintain it at the desired level.
