The PT5634A is a Power Factor Correction control IC for electronic ballast and switching mode power supply application. With a wide bandwidth error amplifier and a wide linear operating range multiplier, the PT5634A is available to operate in Critical Conduction Mode and implement a high PF and excellent THD in wide input voltage application. Furthermore, PT5634A provides a low start-up current and operating current, a precise over-voltage protection and the disable function.
