OB3372
FEATURES
GENERAL DESCRIPTION
- High Power Dual Output PWM Control
- 8V to 35V Input Voltage Range
The OB3372 is a high power dual output LED driver optimized for large size LED backlighting application. It integrates two independent boost converters, providing a high performance and high
- Master/Slave Synchronization Capability
- Programmable 100k Hz~600k Hz Operation Frequency reliability LED backlighting solution.
It incorporates two boost converters operating in
华 current mode PWM control at fixed frequency. The operation frequency is programmed from 100 k Hz to 600 k Hz by setting an external resistor at RT
三 pin.
The OB3372 can be configured for Master-Slave to operation to support multi-channel applications.
The voltage across LED current sense resistor is l regulated to about 600m V to reduce power loss and improve efficiency. tia The external PWM dimming mode is supported.
The PWM dimming signal is injected externally from DIM pin. n The OB3372 offers prehensive protection e...
