C O C O TS19501CB10 Taiwan Semiconductor High Integrated Dimmable LED Controller with Spread Spectrum Frequency Modulation for Automotive Headlight DESCRIPTION FEATURES Operating Ambient Temperature Range -40C to TS19501CB10 is a single channel LED driver of low- 125C side-current sense. This device can operate in DCM, Drives LEDs in Boost, Buck-Boost and SEPIC BCM and CCM mode with full protection and Topology diagnostics. This device is dedicated for and ideally Operation in DCM, BCM, CCM mode suited to automotive headlight. This controller supports Input Voltage 4.5V ~ 38V (42V Abs. Max.) typical topologies such as boost, buck-boost and Adjustable Switching Frequency 70k ~ 700kHz SEPIC. Low-Side Current Sense Internal Voltage Reference 150mV 3.3% Output current regulation is based on average current Both PWM Dimming and Analog Dimming mode control supervised by a control loop. The fault Over Voltage Protection (OVP) flag is connected to pullup resistor from V for DC Over Current Protection (OCP) highlight the information of fault, fault status flag is Over Temperature Protection (OTP) latched by the timer when output is low. Under Voltage Lockout (UVLO) Jitter function for effective spread spectrum to APPLICATION reduce EMI Automotive LED Lighting: High and low Beam, Fault Status flag Daytime Running Light, Turn indicator, Position Internal Soft Start Light, Fog Light Compliant to RoHS Directive 2011/65/EU and in General Lighting Applications accordance to WEEE 2002/96/EC.
