FAN7602C Current Mode PWM Controller.

. . FAN7602C is a current-mode PWM regulator specially designed for off-line power supply, DVDP, VCR, LCD monitor and auxiliary power supply applications. An internal high start-up voltage switch and pulse mode of operation reduce standby power loss. As a result, the input power is less than 1W with an input voltage of 265VAC and a load of 0.5W. Under no-load conditions, the input power is less than 0.15W.Maximum power can be continuously limited, regardless of line voltage changes, using the power limiting function. The switching frequency is not constant and exhibits random frequency fluctuations.TheFAN7602C includes various protection mechanisms to ensure system reliability, and a built-in soft start prevents excessive output voltage rise during startup. Random frequency fluctuation for low electromagnetic radiation (EMI). Internal circuit breaker with high starting voltage. Burst mode of operation (Burst Mode). Reverse line voltage correction to limit maximum power. Protection against voltage below lockout level. Latching protection and internal soft-start function (10 ms). Overload protection. Overvoltage protection. Protection against overheating. Low operating current: 1 mA (typical)SOP- 8-pin housing. Application: Power supply. Power supply for LCD monitor. Auxiliary power supply.
