Maxim Integrated MAX1739EEP T
- Part Number:
- MAX1739EEP T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3260298-MAX1739EEP T
- Description:
- IC CTRLR CCFL BCKLGHT 20QSOP
- ECAD Model:
-
- Datasheet:
- MAX1739EEP T
Description
The MAX1739/MAX1839 are fully integrated controllers designed to drive cold-cathode fluorescent lamps (CCFLs) using the Royer oscillator inverter architecture. This architecture provides near sinusoidal drive waveforms over the entire input range, maximizing the life of CCFLs. The controllers optimize this architecture for a wide input voltage range, high efficiency, and maximum dimming range.
Features
Fast response to input change
Wide input voltage range (4.6V to 28V)
High power-to-light efficiency
Minimizes transformer voltage stress
Lamp-out protection with 2s timeout
Buck switch short and other single-point fault protection
Integrated Royer MOSFET drivers reduce transformer pin count
Buck operation synchronized to Royer oscillator
Synchronizable DPWM frequency
Pin-selectable brightness control interface
SMBus serial interface (MAX1739)
Analog interface (MAX1739/MAX1839)
Applications
Notebook/laptop computers
Car navigation displays
LCD monitors
Point-of-sale terminals
Portable display electronics
