The TPS92520-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 TPS92520-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 between 100-kHz and 2.2-MHz. 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 programming the 10-bit IADJ value via SPI. PWM dimming of LED current is achieved by directly modulating the corresponding UDIM input pin with the desired duty cycle or by enabling the internal PWM generator circuit. The PWM generator translates the 10-bit PWM register value to a corresponding duty cycle by comparing it to a programmable digital counter.
The TPS92520-Q1 incorporates advanced SPI programmable diagnostic and fault protection featuring: cycle-by-cycle switch current limit, bootstrap undervoltage, LED open, LED short, thermal warning and thermal shutdown. An on-board 10-bit ADC samples critical input parameters required for system health monitoring and diagnostics.
The TPS92520-Q1 is available in a 8.1-mm x 11-mm thermally-enhanced 32-pin HTSSOP package with a 2.75-mm x 3.45-mm top-exposed and bottom-exposed pad.

Q1: Are the inventory and prices seen on the platform accurate?
A1: All online products on the shelves can be ordered online, but considering the high liquidity of spot inventory, it is currently impossible to be 100% accurate. If there is any abnormality, you can contact our company online and give the corresponding solution.
Q2: Can you provide the qualification certificate of the original factory or agent?
A2:At present, our own brands are TI, ST, ADI, NXP, LATTICE, CYPRESS, INFINEON, XILINX and other first-line brands. Other channels are original and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.
Q3. Do you test or inspect all goods before delivery?
A3: Yes, we 100% test and inspect all items before shipping.
Q4: What are your payment terms? When will you send me the parts?
A4: Full payment. Goods will be dispatched within 1-5 business days after payment is received.
Q5: How to refund and exchange?
A5:100% money back guarantee or exchange for a similar product.
