The TPS40211QDGQRQ1 is an automotive-qualified, wide-input non-synchronous boost controller from Texas Instruments, engineered for topologies requiring a grounded-source N-channel FET including boost, flyback, SEPIC, and LED driver applications. Operating from a 4.5V to 52V input range with a 260mV reference voltage optimized for current-regulated designs, this AEC-Q100 Grade 1 qualified device supports output voltages from 4.5V up to 300V with a 95% maximum duty cycle.
The controller features fixed-frequency current-mode control with internal slope compensation, programmable closed-loop soft start, overcurrent protection with automatic retry, and an adjustable oscillator with external synchronization capability. Housed in a 10-HVSSOP (DGQ) package, the device is functional safety-capable and operates across -40°C to +125°C ambient, targeting infotainment, cluster, body electronics lighting, and HEV/EV powertrain applications.
Applications
● Automotive LED lighting and headlamp drivers where current-mode regulation with 260mV reference minimizes sense-resistor losses.
● Infotainment and instrument cluster power supplies in vehicle cockpit electronics.
● Automotive body electronics lighting modules and interior illumination control.
● HEV/EV and powertrain systems requiring high-voltage boost conversion up to 300V output.
● Industrial control systems and battery-powered equipment using boost, flyback, or SEPIC topologies.
FAQs
Q: What is the difference between TPS40210-Q1 and TPS40211-Q1? A: The primary difference is the reference voltage - TPS40210-Q1 uses 700mV for voltage regulation, while TPS40211-Q1 uses 260mV, making it better suited for current-regulated applications like LED drivers.
Q: What package and pinout does the TPS40211QDGQRQ1 use? A: A 10-pin HVSSOP (DGQ) PowerPAD package measuring 3mm x 4.9mm, with pins including RC, DIS/EN, SS, COMP, FB, BP, GND, ISNS, GDRV, and VDD.
