Working Principles

The FAN4800CMY is a voltage mode PWM controller IC used in power management applications. It operates by comparing the feedback voltage from the FB pin with a reference voltage to regulate the output voltage. The error amplifier amplifies the difference between these voltages, which is then fed into the PWM comparator. The PWM comparator generates a pulse-width modulated signal that controls the duty cycle of an external power switch, thereby regulating the output voltage.

Detailed Application Field Plans

The FAN4800CMY is commonly used in various power management applications, including but not limited to: - DC-DC converters - Voltage regulators - Power supplies for consumer electronics - LED drivers - Battery chargers
