Overview

Preliminary BW7385A High Power Factor & Accuracy Constant Current LED Driver Features TM (Transition Mode) Fixed On -Time PFC Control Accuracy Constant Current Low BOM Cost Inductor Size Reduction CT Pin Adjust Frequency Range for Optimization Over Voltage Protection (OVP)-Auto Recovery LED Short Protection (SCP) -Auto Recovery Over Load Protection (OLP) -Auto Recovery SOT-26 Package Compatible Inductance Ballast Incompatible Electronic Ballast Description The BW7385A is a highly-integrated, low startup current, TM (Transition Mode), fixed on- time PFC control and PWM controller.
These functions enable the LED driver to easily meet the accuracy average LED current and high power factor requirements.
The integrated functions also include the LED short protection, over voltage protection, over load protection.
The COMP pin controls the duty by connected an RC compensation network to ground and forming the closed loop feedback control.
The BW7385A improves the performance and reduces t...
