BIT3251 PWM Controller led driver SOP-8 SMD IC BB11
Description :
The BIT3251 is a high frequency PWM controller integrates required fuctions for boost conversion in a small SOP-8 package. A low 0.2V feedback voltage and over voltage protection make the BIT3251 be an ideal controller for LED backlight supplies. CMOS process greatly reduces the operating current when comparing to similar products.
Features:
Voltage Mode PWM Controller
Low 0.2V reference Voltage
330KHz Operation
Over Voltage Protection
Internal Soft-Start
Internal UVLO (Under Voltage Lock Out)
Limited Output Duty Cycle
Low Shutdown current (0.1uA)
CMOS Totem Pole Output
SOP-8 Package
Absolute Ratings:(ifTa=25)
VDD:-0.3 ~ +8 V
GND:0.3 V
Input Voltage:-0.3 ~ VDD+0.3 V
Operating Ambit Temperature:0 ~ 70
Extreme Operating Ambient Temp:-40 ~ 85
Operating Junction Temperature:+150
Storage Temperature:-55~ 150
Recommended Operating Condition:
Supply Voltage:4~ 8 V
Operating Frequency:330KHz
Operating Ambient Temperature:0 ~ 70
