Use this economy primary side pwm UCC2809P-2 secondary side PWM controller from Texas Instruments to control your system directly with the system load. This secondary side synchronous controller's single output can produce a current up to 0.8 A. Its switching regulator has a frequency of 1000 kHz. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This secondary side synchronous controller's maximum duty cycle is 70(Typ) %. This secondary side synchronous controller has a minimum operating temperature of -40 °C and a maximum of 85 °C.
