OZ9933 電子部品, 半導体
OZ9938
FEATURES
• Positive PWM dimming polarity
• Constant operating frequency
• Drives positive/negative-impedance lamps during ignition
• High drive current for external MOSFETs
• User-defined ignition time and shutdown delay time
• Multiple mode dimming control
• Built-in intelligence for lamp ignition and normal operation of CCFLs
• Open-lamp and over-voltage protection
• Soft start function
GENERAL DESCRIPTION
The OZ9938 is a high performance, cost-effective Cold Cathode Fluorescent Lamp
(CCFL) controller designed to drive large-size LCD applications requiring 2 to 6
CCFLs.
This controller converts an unregulated DC voltage into a nearly sinusoidal lamp volt-
age and current waveforms. It provides two drive signals for most power conversion
topologies, while maintaining high efficiency operation.
The OZ9938 offers a high level of integration, while maintaining flexibility and high
efficiency operation that reduces external component heating. This results in higher
reliability and longer CCFL life. The proprietary design technique provides a simple,
low-cost system solution.
APPLICATIONS
• LCD Monitor

OZ9928
FEATURES
• Dual CCFL inverter controller
• Synchronization for multiple ICs
• Supports differential drive
• Supports system operation frequency synchronization
• Constant operating frequency
• 180 degree phase-shift PWM dimming
• Mixed-mode dimming control
• Integrated high side N-MOSFET driver
• High drive capability
• Selectable shutdown protection mode
• User-defined ignition and shutdown delay timers
• Built-in intelligence for lamp ignition and normal operation of CCFLs
• Open-lamp and over-voltage protection
• Soft start function
GENERAL DESCRIPTION
The OZ9928 is a high performance, cost-effective, 2-channel controller designed for
large-size Cold Cathode Fluorescent Lamp (CCFL) or External Electrode Fluorescent
Lamp (EEFL) LCD TV applications.
The controller provides six drive signals and is capable of driving full-bridge and
Class-D topologies. The drive outputs are fixed phase when used for single-side or
differential drive applications. Multiple OZ9928s can be synchronized to drive numer-
ous lamps.
OZ9928 provides total system protection for differential drive and single-side drive
applications. It receives either a DC voltage and/or external Pulse Width Modulation
(PWM) signal to perform mixed-mode PWM dimming.
APPLICATIONS
• LCD TV
