General Description

 

ME8204 is a highly integrated current mode PWM control IC optimized for high performance, low standby power (<100mW) and cost effective offline flyback converter applications in 40W~60W range. ME8204 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), CS short protection, over load protection (OLP), and VDD under voltage lockout (UVLO) and latch feature including over temperature protection (OTP), over voltage (fixed or adjustable) protection(OVP). Excellent EMI performance is achieved with frequency shuffling technique together with soft switching control at the totem pole gate drive output. Tone energy at below 20KHz is minimized in the design and audio noise is eliminated during operation.

 

Features

 

●Power on Soft Start Reducing MOSFET VDSStress

●Frequency shuffling for EMI

●Audio Noise Free Operation

●Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design

●Internal Synchronized Slope Compensation

●Fixed 65KHz Switching Frequency (8204, 8204B)

●Fixed 100KHz Switching Frequency (8204C)

●Good protection coverage with auto self-recovery

﹡VDD Under Voltage Lockout with Hysteresis (UVLO)

﹡Over Temperature Protection (OTP) with latch shut down(8204) or auto-recovery(8204B,8204C)

﹡Cycle-by-cycle over current threshold setting for constant output power limiting over universal input voltage range

﹡Overload Protection (OLP) with auto-recovery

﹡VDD Over voltage Protection(OVP) with latch shut down(8204) or auto-recovery(8204B.8204C)

﹡Adjustable OVP through external Zener

﹡CS floating protection with auto-recovery

﹡CS short protection with auto –recovery
