Sprinter micropower step-up DC / DC converter is smaller than 50 mm2

In Electronic Infomation Category: R | on November   1, 2010

Linear Technology Corporation (Linear Technology) launched 1A, 1.2MHz Micropower Step-Up DC / DC converter - LT3473, the device is flat DFN package, with integrated Schottky diode and FDS9933A datasheet and output disconnect circuitry. Small package size, high integration, and FDS9933A price and the use of tiny SMT components enable solution size is less than 50mm 2 .

LT3473s 2.2V to 16V input voltage range makes it capable of single-cell Li-ion battery to up to fixed 15V input rails as the power supply to provide up to 34V output. The constant 1.2MHz switching frequency allows designers to keep switching noise in the noise-sensitive circuitry, and FDS9933A suppliers and can use tiny capacitors and inductors. Internal 1A switch allows the device from the 25V lithium-ion battery provides up to 80mA of current when the order for OLED and TFT display applications. Automatic Burst Mode (Burst Mode) will work in the no-load quiescent current to 150μA, maximizing battery run time. An auxiliary reference input (CTRL) allows the user to use any low voltage to replace the internal 1.25V feedback reference, the output voltage to ensure full control during operation. Other features include a power good flag and thermal shutdown.

LT3473A includes two additional NPN transistors for generating intermediate bias voltages from the output. The device uses 4 × 3mm DFN-12 package. LT3473 does not include these NPN transistors, using 3 × 3mm DFN-8 package. Both devices are available from stock. 1,000-piece quantities, LT3473 starts at $ 1.95 per piece, while the LT3473A starts at $ 2.05 per unit, the above prices are for reference only.
