onsemi NCP1200
the NCP1200 represents a major leap toward ultra−compact Switchmode Power Supplies. With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz, the controller drives low gate−charge switching devices like an IGBT or a MOSFET thus requiring a very small operating power. Due to current−mode control, the NCP1200 drastically simplifies the design of reliable and cheap offline converters with extremely low acoustic generation and inherent pulse−by−pulse control.| Part No. | NCP1200 |
