OB3350CPA Description

Short technical summary and product information.

The OB3350CPA is a highly integrated and cost-effective LED driver optimized for LCD monitor and LCD TV backlighting applications. It provides a high-performance LED backlight solution with minimized BOM count.

The device contains a PWM boost driver that uses current mode control and fixed frequency operation to regulate LED current. The LED current is sensed through an external current sense resistor. The OB3350 offers an external low-frequency PWM (LPWM) dimming method for a wide range of dimming control.

Key features include comprehensive protection mechanisms such as power MOSFET over current protection (OCP), output over voltage protection (OVP), IC power supply under voltage lockout (UVLO), and LED open protection. The OB3350 is offered in an SOP-8 package, suitable for surface mount applications.

Applications include LCD monitors, LCD TVs, and flat panel displays. The operating ambient temperature range is -40°C to 85°C, with a junction temperature range of -40°C to 150°C.
