PWM CONTROLLER, SMD, 3846, SOIC16; Controller Type:PWM; Voltage, Input Max:40V; Output Current Max:500mA; Output Type:Totem Pole; Frequency:500kHz; Power Dissipation:1000mW; Voltage, Supply Min:8V; Voltage, Supply Max:40V;
The UC3823A and UC3823B and the UC3825A andUC3825B family of PWM controllers are improved versions of the standard UC3823 and UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth productis 12 MHz, while input offset voltage is 2 mV. Current limit threshold is assured to a tolerance of 5%. Oscillator discharge current is specified at 10 mA for accurate dead time control. Frequency accuracy is improved to 6%. Startup supply current, typically 100 t,A, is ideal for off-line applications. The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of2-A peak currents during transitions.
