Working Principle

The ZL2106 operates with synchronous rectification, pulse width modulation and phase lock loop control techniques. It has an internal MOSFET which switches the output voltage in a constant frequency PWM mode, based on an internal phase lock loop. This results in low noise operation, fast transient response and excellent power conversion efficiency.

The device has on-chip MOSFETs which control and output the power stages. The feedback control loop consists of an internal error amplifier, internal voltage reference and an internal oscillator. This loop enables the device to achieve accurate and stable output voltage with load and line variations.

The device also has integrated fault protection features, including over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), thermal protection (TP) and short-circuit protection (SCP). These features help to limit the output current and protect the device from any damage.

The ZL2106 is an ideal solution for applications that require a reliable and efficient DC-DC switching regulator with high efficiency and low noise operation.
