UCD3138: Totem pole PFC

Part Number: UCD3138

 Hello guys,

 One of our customer is interested in Totem-pole PFC for their product.

 Do you have any reference schematic for Totem-pole PFC?

 Also do you have any recommended TI device for Totem-pole PFC with higher efficiency and lower cost?

 Your reply would be appreciated.

 Best regards,

 Kazuya Nakai.
