INTRODUCTION: The CE9302 is a step down constant current high brightness LED driver which provide a cost effective design solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs, and other LED illumination applications. The CE9302 operate from a 6.5V to 30V input voltage range. A high-side current-sense resistor adjusts the output current up to 1A and a dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state. A hysteretic control method ensures excellent input supply rejection and fast response during load transients and PWM dimming. FEATURES: z Up to 97% Efficiency Power Supply Voltage: 6.5V-30V Simple Low Parts Count Maximum PWM Dimming Frequency: 50kHz Up to 1MHz Switching Frequency Hysteretic Control: No Compensation Single Pin on/off and Brightness Control Using DC Voltage or PWM Inherent Open Circuit LED Protection Typical 5% Output Current Accuracy Soft-Start Limit In-Rush Current Over-Thermal Protection -40°C to +85°C Temperature Range space-saving SOT89-5 or ESOP8 package APPLICATIONS： Architecture Detail lighting Constant Current Source Hand-held lighting Portable Consumer Devices ORDER INFORMATION:CE9302①② DESIGNATOR SYMBOL DESCRIPTION ① A Standard ② S Package：ESOP8 P Package：SOT-89-5
