TPS61161DRVR With a 40-V rated integrated switch FET, the TPS61160 and TPS61161 are boost converters that drive LEDs in series. The boost converters run at 600-kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allow for the use of small external components.
TPS61161DRVR The default white LED current is set with the external sensor resistor RSET, and the feedback voltage is regulated to 200 mV, as shown in the . During the operation, the LED current can be controlled using the one-wire digital interface (EasyScale protocol) through the CTRL pin. Alternatively, a pulse width modulation (PWM) signal can be applied to the CTRL pin through which the duty cycle determines the feedback reference voltage. In either digital or PWM mode, the TPS61160 and TPS61161 do not burst the LED current; therefore, they do not generate audible noises on the output capacitor. For maximum protection, the device features integrated open LED protection that disable the TPS61160 and/or TPS61161 to prevent the output voltage from exceeding the device's absolute maximum voltage ratings during open LED conditions.

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.
