The TPS92519-Q1 is a monolithic dual synchronous buck LED driver with a wide 4.5-V to 65-V operating input voltage range that can independently power two strings of series connected LEDs. The TPS92519-Q1 implements an adaptive on-time average current mode control and is designed to be compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps. The adaptive on-time control provides near constant switching frequency that can be set using FSET input. Inductor current sensing and closed-loop feedback enables better than ±4% accuracy over wide input voltage, output voltage and ambient temperature range.

The high performance LED driver can independently modulate LED current using both analog or PWM dimming techniques. Linear analog dimming response with over 16:1 range is obtained by varying the voltage from 140 mV to 2.45 V across the high Impedance Analog Adjust (IADJ) input. PWM dimming of LED current is achieved by directly modulating the corresponding UDIM input pin with the desired duty cycle and frequency. The device supports high frequency shunt FET dimming and is compatible with pixel control techniques using LED matrix manager.

The TPS92519-Q1 supports parallel operation of two or more channels thus enabling flexibility required to drive high current LEDs or laser diodes. Current is shared between parallel channels based on IADJ input independent of component tolerances and parasitics.

The TPS92519-Q1 incorporates advanced fault protection featuring: cycle-by-cycle switch current limit, bootstrap undervoltage and thermal shutdown. The device includes an open drain fault output to indicate output open and short conditions.

The TPS92519-Q1 is available in a 8.1-mm × 11-mm thermally-enhanced 32-pin HTSSOP package with a 2.75-mm × 3.45-mm bottom-exposed pad.
