Description
The OZ9910ASN is a high-efficiency pulse-width modulation (PWM) controller designed for both DC/DC and DC/AC high voltage applications. Devices such as magnetrons and traveling wave tubes (TWT) require a bias voltage up to several thousand Volts DC and Cold Cathode Fluorescent Lamp (CCFL) requires several hundred to thousand Volts AC to operate. The OZ9910, dual forward PWM controller, is optimized for such applications.
OZ9910 supports a wide input voltage range and provides a constant, user-defined, operating frequency, ensuring that the load operates at a fixed frequency. In display systems, a single operating frequency eliminates interference among the lamps and the display panel. In radar systems, a single operating frequency avoids any influence by alias signals.
Features:
• Controller for high-voltage DC/DC and DC/AC converters
• High-efficiency, zero voltage switching dual forward controller
• Feed forward compensation
• Combined analog and/or PWM control modes for wide-range load regulation
• Supports wide input voltage range
• Constant operating frequency
• Soft start function
• Built-in open-load protection, over-voltage protection and over-current protection
• Built-in under-voltage lockout function
• Low stand-by power
• Toggle ENA pin to reset IC
