产品介绍

Current Mode PWM Controller With Frequency Shuffling ME8204BM6G
ME8204BM6G Description Features
Typical Application
Offline AC/DC flyback converter for
? AC/DC adapter
? PDA power supplies
? Digital cameras and camcorder adapter
? VCR,SVR, STB, DVD&DVCD player SMPS
? Set-top box power
? Auxiliary power supply for PC and server
? Open-frame SMPS
ME8204BM6G 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.
●Power on Soft Start Reducing MOSFET VDS Stress
●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)
