GENERAL DESCRIPTION
High Power Dual Output PWM Control 8V to 35V Input Voltage Range It integrates two independent boost converters, providing a high performance and high Master/Slave Synchronization Capability Programmable 100kHz~600kHz Operation Frequency reliability LED backlighting solution. The operation frequency is programmed from 100 kHz to 600 kHz 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 600mV 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 comprehensive protection e such as power MOSFET over current protection (OCP), output over voltage protection (OVP), IC fid power supply under voltage lockout (UVLO), and LED open & short protection.
