Brief Description of OB3350CP

The OB3350CP is a highly integrated and cost-effective LED driver IC, primarily optimized for backlighting in LCD monitors and LCD TVs. It incorporates a PWM (Pulse Width Modulation) boost driver which utilizes current mode control and fixed frequency operation to regulate constant current through LEDs. The IC is designed to work with external power switches like MOSFETs to drive the LEDs.

Here are some key features and specifications of the OB3350CP:

Current Mode PWM Controller: It offers good dynamic response and maintains constant LED current.
Input Voltage Range: The operating voltage range is quite wide, from 8V to 35V, making it versatile for different applications.
PWM Dimming Mode: It supports external PWM signals for dimming control, allowing the brightness of LEDs to be adjusted.
Protection Features: The IC includes over-voltage protection, over-current protection, under-voltage lockout (UVLO), and thermal shutdown, ensuring the safety and reliability of the LED driver system.
Operating Current: It operates with a supply current of 3 mA (maximum) and a standby current of 400 µA (maximum).
PWM Frequency: The PWM operating frequency is between 175 KHz and 275 KHz.
For using the OB3350CP, an external MOSFET would typically be used as a switch to regulate the LED current, with the IC’s gate terminal controlling the MOSFET. Inductors are used in the circuit to ensure the stability of the DC current to the LEDs. It also features a current sense terminal for LED current monitoring and a compensation terminal for boost converter loop compensation.

This IC is often utilized in applications beyond just LCD monitors and TVs, such as flat panel displays and various LED driver circuits.
