TS19503CB10H Taiwan Semiconductor 2A, Step-Down LED Driver with Integrated N-channel FET High-Side Current Sense, PWM and Analog Dimming Capability DESCRIPTION FEATURES The TS19503 is a continuous conduction mode ● AEC-Q100 qualified with the following results: Device temperature grade 1: -40°C to 125°C Device HBM ESD classification level H1C Device CDM ESD classification level C6 ● Input voltage range 4.5V to 75V ● Hysteretic Control: No Compensation ● Internal N_MOSFET with 200mΩ Low RDS(ON) ● 2A Output Current ● Up to 97% Efficiency ● Typical ±2% LED Current Accuracy ● DIM Pin for Analog Dimming and PWM Dimming ● 1000:1 Dimming ● Single pin on/off and brightness control using PWM ● Up to 1MHz switching frequency ● High-Side Current Sense ● FLT Pin for MCU ● Over Temperature Protection ● Open Load Flag ● RoHS Compliant ● Halogen-Free according to IEC 61249-2-21 inductive step-down converter, designed for driving single or multiple LEDs. It operates from an input supply between 4.5V and 75V. It provides a high accuracy output current externally adjustable up to 2A. Depending upon the supply voltage and external components, the TS19503 can provide more than 25 watts of output power. The TS19503 includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output. A dedicated DIM input accepts a wide range of inputs. Applying a voltage of 0.1V or lower to the DIM pin turns the output off and switches the device into a low current standby state. The device also provides a FLT flag when an open load or over temperature condition is detected.
