TEXAS INSTRUMENTS TPS61040QDBVRQ1 发光二极管驱动器, 1输出, 升压逐步上升, 1.8V-6V输入, 1MHz开关, 28V/90mA输出, SOT-23-5
The is an Automotive Catalogue Low-power 400mA DC/DC Boost Converter dedicated for small to medium LCD bias supply and white LED backlight supplies. The device is ideal to generate output voltages up to 28V from a dual cell NiMH/NiCd or a single cell Li-ion battery. The part can also be used to generate standard 3.3/5 to 12V power conversions. The high-frequency boost converter operates with a switching frequency up to 1MHz. This allows the use of small external components using ceramic as well as tantalum output capacitors. The TPS61040 has an internal 400mA switch current limit, offering lower output voltage ripple and allows the use of a smaller form factor inductor for lower power applications. The low quiescent current typically 28µA together with an optimized control scheme, allows device operation at high efficiencies over the entire load current range.
IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
