Description

The BIT3260 is a high frequency PWM controller integrating required functions for boost conversion in a small SOP-8 package. A low 0.2V feedback voltage and over voltage protection make BIT3260 an ideal controller for LED backlight supplies. CMOS process greatly reduces the operating current compared with similar products.

Features

1. Voltage Mode PWM Controller
2. 10V ~ 18V operation voltage
3. Current limit
4. Frequency adjustable
5. Internal Soft-Start
6. Maximum duty cycle output
7. Over temperature protection, OTP
8. Internal Under Voltage Lock Out, UVLO
9. Totem Pole Output
