PRODUCTION DATA. TPS61193-Q1 SNVSAM9 – AUGUST 2016 TPS61193-Q1 Low-EMI Automotive LED Driver With Three 100-mA Channels 1 1 Features 1 • Qualified for Automotive Applications • AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to +125°C Ambient Operating Temperature • Input Voltage Operating Range 4.5 V to 40 V • Three High-Precision Current Sinks – Current Matching 1% (Typical) – LED String Current up to 100 mA per Channel – Outputs can be Combined Externally for Higher Current Capability • High Dimming Ratio of 10 000:1 at 100 Hz • Integrated Boost/SEPIC for LED String Power – Output Voltage up to 45 V – Switching Frequency 300 kHz to 2.2 MHz – Switching Synchronization Input – Spread Spectrum for Lower EMI • Extensive Fault Detection Features – Fault Output – Input Voltage OVP, UVLO, and OCP – Open and Shorted LED Fault Detection – Thermal Shutdown • Minimum Number of External Components space Simplified Schematic 2 Applications • Backlight for: – Automotive Infotainment – Automotive Instrument Clusters – Smart Mirrors – Heads-Up Displays (HUD) – Central Information Displays (CID) – Audio-Video Navigation (AVN) 3 Description The TPS61193-Q1 is an automotive high-efficiency, low-EMI, easy-to-use LED driver with an integrated DC-DC converter. The DC-DC converter supports both boost and SEPIC mode operation. The device has three high-precision current sinks that can be combined for higher current capability. The DC-DC converter has adaptive output voltage control based on the LED current sink headroom voltages. This feature minimizes the power consumption by adjusting the voltage to the lowest sufficient level in all conditions. For EMI reduction DC-DC supports spread spectrum for switching frequency and an external synchronization with dedicated pin. A wide-rage adjustable frequency allows the TPS61193-Q1 to avoid disturbance for AM radio bands. The input voltage range for the TPS61193-Q1 is from 4.5 V to 40 V to support automotive stop/start and load dump condition. The TPS61193-Q1 integrates extensive fault detection features.
