AX6228
Current Mode PWM Power Switch
GENERAL DESCRIPTION
AX6228 combines a dedicated current mode PWM controller with a high voltage
power MOSFET. It is optimized for high performance, low standby power, and cost
effective off-line flyback converter applications in under 16W range.
AX6228 offers complete protection coverage with automatic self-recovery feature
including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), VDD over
voltage clamp and under voltage lockout (UVLO). Excellent EMI performance is achieved
with proprietary frequency shuffling technique together with soft switching control at the
totem pole gate drive output.
The tone energy at below 20KHZ is minimized in the design and audio noise is
eliminated during operation. AX6228 is offered in PDIP-8L package.
FEATURES
- Power on Soft Start Reducing MOSFET VDS Stress
- Frequency Shuffling for EMI
- Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power
Design
- Audio Noise Free Operation
- Fixed 50KHZ Switching Frequency
- Internal Synchronized Slope Compensation
- Low VDD Startup Current and Low Operating Current
- Leading Edge Blanking on Current Sense Input
- Good Protection Coverage With Auto Self-Recovery
VDD Over Voltage Clamp and Under Voltage Lockout with Hysteresis (UVLO)
Line Input Compensated Cycle-by-Cycle Over-current Threshold Setting for
Constant Output Power Limiting Over Universal Input Voltage Range
Overload Protection (OLP)
Over Voltage Protection (OVP)
- Compatible with OB2358/CR6228
- Pb-Free PDIP-8L
