Texas Instruments Standard Linear and Logic UC3843AD

Description
The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler. Number of PWM Outputs = 1 Control Method = Current Topology = Boost, Buck, Flyback, Forward Rise Time = 50ns Fall Time = 50ns Maximum Duty Cycle = 100% Maximum Switching Frequency = 500 kHz Mounting Type = Surface Mount Package Type = SOIC Pin Count = 14
