Due to the large price fluctuation of electronic components and components, the display price cannot be used as the final transaction price. Please refer to the customer service for inquiry. Because our company has a large number of sales models, the products that cannot be put on the shelf in time, if you cannot find the materials you need, please contact the online customer service or thank you Number of channels (#)2TopologyBoost Controller, Buck Controller, Buck-Boost Controller, Flyback Controller, Sepic ControllerRatingAutomotiveOperating temperature range (C)-40 to 125 Approx. price (USD) 1ku | 3.422 Vin (Min) (V)4Vin (Max) (V)40Vout (Min) (V)4Vout (Max) (V)75Iout (Max) (A)1.5Iq (Typ) (mA)8Switching frequency (Max) (kHz)600FeaturesAdjustable Switch Frequency, Enable/Shutdown, Soft Start, Synchronization Pin, Thermal Shutdown The TPS9260x-Q1 family of devices is a single-channel and dual-channel high-side-current LED driver. With full protection and diagnostics, this family of devices is dedicated for and ideally suited to automotive front lighting. The base of each independent driver is a peak-current-mode boost controller. Each controller has two independent feedback loops, a current-feedback loop with a high-side current-sensing shunt and a voltage-feedback loop with an external resistor-divider network. The controller delivers a constant output voltage or a constant output current. The connected load determines whether the device regulates a constant output current (if the circuit reaches the current set-point earlier than voltage set-point) or a constant output voltage (if the circuit reaches the voltage set-point is reached first, for example, in an open-load condition). Each controller supports all typical topologies such as boost, boost-to-battery, SEPIC, or flyback. Uses of the high-side PMOS FET driver are for PWM dimming of the LED string and for cutoff in case of an external short circuit to GND to protect the circuit.
