8Pin CURRENT MODE PUSH-PULL PWM CONTROLLERS WITH PROGRAMMABLE SLOPE COMPENSATION
DESCRIPON
The UCC38083/4/5/6 is a family of BiCMOS pulse width modulation PWM controllers for dc-to-dc or off-line fixed-frequency current-mode switching power supplies. The dual output stages are configured for the push-pull topology. Both outputs switch at half the oscillator frequency using a toggle flip-flop. The dead time between the two outputs is typically 110 ns, limiting each output’s duty cycle to less than 50%.
