Overview
PT2206 Primary Side Constant Voltage Regulator GENERAL DESCRIPTION The PT2206 is a high performance AC/DC power supply regulator which integrates a 730V power switch.
The PT2206 operates in quasi-resonant mode at heavy load to provide high efficiency along with a number of key built-in protection features while minimizing the external component count, and lowering the total bill of material cost.
The PT2206 removes the need for secondary feedback circuitry while achieving excellent line and load regulation.
It also eliminates the need for loop compensation components while maintaining stability at all operating conditions.
The device uses PFM technology to enableoptimized transformer design in off-line applications over a wide input voltage range.
Excellent EMI performance is achieved with frequency jittering function.
The ultra-low operating current at light load ensures that the PT2206 is ideal for applications targeting the newest regulatory standards for average efficiency and standby power.
The PT2206 is available in an SOP-8 and DIP8 package z z z z z z z z z z FEATURES z Primary-side feedback eliminates opt-isolators and simplifies design Quasi-resonant operation for high efficiency Complies with CEC/EPA no-load power consumption and average efficiency regulations Integrate 730V power switch No external compensation components required Built-in programmable line voltage detection Frequency jittering for better EMI performance Over current protection(OCP) Over load protection(OLP) VDD over voltage protection (OVP) Over temperature shut down APPLICATIONS z z z z z DVD/STB power supply AC/DC adapter/chargers for cell phones, PDAs, digital still cameras AC/DC adapters for consumer electronics Auxiliary supplies for TV/PC power supply Home appliances, white goods and consumer electronics ORDERING INFORMATION PACKAGE SOP8 DIP8 TEMPERATURE RANGE -20℃ to 85℃ -20℃ to 85℃ ORDERING PART NUMBER PT2206ESOH PT2206EDIH TRANSPORT MEDIA Tape and Reel Tube MARKING PT2206...
