Dezhou Instruments company (TI) has introduced its claim as "the first industry" monolithic staggered PWM controller, in computer servers, telecommunications, data communications and consumer products (such as plasma display panels) used in the offline And DC / DC converters used in the 50 ~ 100 A high current power supply.

　　TI's UCC28220-and UCC28221-peak current controller of the staggered use of advanced technology for the control of two isolated power level, in order to maximize the power density, lower output current volatility and improve transient response. This can in front of two staggered can reverse staggered structure in the use of the device, there are two integrated RP-PWM channels, in ord er to control a large current output. They can be the most precise control of the air factor, the program, each channel can control the factor of air in 60 to 90%.

　　UCC28220 16 pin SOIC and small form TSSOP packages. High-voltage circuit UCC28221 start in a 16 pin SOIC package and slightly larger that the 20 pin TSSOP package, so that the high voltage pin spacing with UL1950 "leakage gap" security requirements.
