SMP212 Datasheet - Power Integrations, Inc

Description
   The SMP212, intended for 220 V or universal off-line isolated power supply applications, combines a high voltage power MOSFET switch with a switchmode power system controller in a monolithic integrated circuit. Few external components are required to implement a small, low-cost, isolated, off-line power supply.

Product Highlights
Integrated Power Switch and CMOS Controller
• Output power up to 10 W from rectified 220 VAC input, 5 W from rectified universal (85 to 265 VAC) input
• External transformer provides isolated output voltages
• Integrated solution minimizes overall size

High-voltage, Low-capacitance MOSFET Output
• Designed for 120/220 V off-line applications
• Can also be used with DC inputs from 36 V to 400 V
• Low capacitance allows for high frequency operation

High-speed Voltage-mode PWM Controller
• Internal pre-regulator self-powers the IC on start-up
• Wide VBIAS voltage range
• Designed for use with optocoupler feedback

Built-In Self-protection Circuits
• Adjustable cycle-by-cycle current limit
• Latching shutdown can be used for output overvoltage protection
• Shutdown/auto-restart cycling
• Input undervoltage lockout
• Thermal shutdown
