GENERAL DESCRIPTION
The OZ9910 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 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
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.
The OZ9910 provides a wide-range load
regulation through low-frequency LPWM and/or
analog-adjust dimming controls. It also provides
an option for selecting a different turn-on
frequency from the operation frequency that is
suitable for loads such as CCFL and TWT.
The OZ9910 provides a built-in feed-forward
compensation function for applications requiring a
wider, dynamic input voltage range. The
feed-forward compensation feature optimizes line
and load regulation.
To avoid over-shoot and in-rush current to both
input and output loads during start up, a soft start
function is provided to improve system reliability.
The controller provides open-load protection,
over-voltage protection and over-current
protection. The striking time (turn-on) for
open-load protection is user-defined.
OZ9910 provides under-voltage lockout protection
and will disable the IC if VIN falls below a
threshold. OZ9910 resumes normal operation
when VIN exceeds the threshold.
To reset the IC, toggle the ENA pin. OZ9910
operates with a standby current of approximately
80uA.
