Description

The ICE1QS01 is optimized to control free running flyback converters with and without Power Factor Correction (with PFC Charge Pump).

The switching frequency is reduced in small steps with decreasing load towards a minimum of 20 kHz in standby mode. This function is performed by a digital circuit to avoid any jitter also with periodically pulsed loads. To provide extremely low power consumption at light loads, this device can be switched into Standby Burst Mode. This is also possible without standby control signal (for adapter application).

OZ9936 Datasheet PDF – CCFL Inverter Controller – O2Micro

Posted on by pinout

Part Number: OZ9936

Function: LCD Monitor CCFL Inverter Controller

Package: SOIC, PDIP 8 Pin type

Manufacturer: O2Micro International

OZ9936 datasheet

 

Description

The patent pending OZ9936 is a cost-effective CCFL (Cold Cathode Fluorescent Lamp) Power Management controller designed for driving CCFLs in Liquid Crystal Display (LCD) applications.

The OZ9936 provides two drive signals for most power conversion topologies, such as push-pull, half-bridge, full-bridge or Class-D inverters while maintaining high-efficiency operation. The highly integrated controller provides current and voltage regulation, soft-start operation, over-voltage protection and an external enabling function while maintaining a high-degree of design flexibility. The application requires a minimum number of off-the-shelf components.
