Working Principle:

The high-efficiency and reliable switching operations provided by EL7535IYZ-T13 are based on the PWM current-mode architecture. The component provides a 10-bit 2.5V reference regulator, which is used to regulate the voltage applied to the current-sense resistor connected in the feedback path. The voltage across the current-sense resistor is then compared to the reference voltage, which results in a voltage error signal. This error signal is used to drive the power MOSFET with a pulse width modulated control signal.

The PWM modulated control signal ensures that the component is able to provide accurate and efficient control of the output voltage. The component also features an integrated cycle-by-cycle current-limit, which provides safe and reliable operation by limiting the peak switch current to a safe level. In addition, the component also provides an external sync frequency up to 1MHz, which allows the component to be used in a wide range of applications.
