Introduction
High-performance current-mode PWM controller designed for cost-effective AC/DC converters, delivering up to 12W continuous output power (18W for ME8115B) across a wide input voltage range of 85–265V, with peak output power up to 18W. An optimized, highly rational circuit design combined with a cost-effective bipolar process minimizes overall product cost. This power controller operates in a typical flyback topology to form a compact AC/DC converter. The internal startup circuit employs a unique current-sinking approach, utilizing the inherent amplification of the power switch transistor to complete startup (Ic-to-Ib amplification of the switching transistor), which significantly reduces power dissipation in the startup resistor. At lower output power levels, the IC automatically reduces its operating frequency to achieve ultra-low standby power consumption. When VCC reaches 10V, the internal OVP activates to clamp the output voltage, preventing excessive output voltage caused by optocoupler or feedback circuit failure. The IC also provides comprehensive overload protection and anti-saturation functions, offering real-time protection against overload, transformer saturation, and output short-circuit conditions to enhance power supply reliability. An integrated thermal protection with hysteresis shuts down the output when the chip overheats. The current limit can be set by external resistor Rs.
