Description

The OZ9910 is a high-efficiency pulse-width modulation (PWM) controller designed for both DC/DC and DC/AC high voltage applications. A dual forward PWM controller refers to a specific type of controller circuit that is designed for controlling and regulating power in a forward converter topology

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 operates in a zero-voltage switch mode through the dual forward topology utilizing free-wheeling diodes. The IC operates in a constant frequency mode that minimizes electromagnetic interference (EMI). In addition, OZ9910 achieves a high power-conversion efficiency resulting in lower power dissipation and higher system reliability that are critical for radar transmitters and display systems
