Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
The wide input capability of 4 to 80V makes these devices ideal for automotive, 48V telecomms backup supplies and industrial control applications.
Additionally, their very low quiescent current as low as 40uA (operating) make them an excellent choice for battery-powered "keep alive" systems that require extended run times.
The LT3013B's power-good flag features programmable delay to indicate output regulation.
For high voltage applications that require large input-to-output differentials, the LT3012B and LT3013B offer a highly compact and thermally effective solution.
The DFN and TSSOP packages provide thermal performance on a par with much larger conventional packages.
The LT3012B and LT3013B operate with very small, low cost ceramic output capacitors.
They are stable with only a 3.3uF output capacitor compared with older regulator devices requiring between 10 and 100uF.
The LT3012B and LT3013B do not require added series resistance common to other regulators.
Internal protection circuitry includes reverse-battery protection, current limiting thermal limiting and reverse-current protection.
The LT3012BEDE/LT3013BEDE and LT3012BEFE/LT3013BEFE are available with a wide-ranging adjustable output from 1.24 to 60V.
Available from stock, the devices are offered in the low profile (0.75mm) 12-lead DFN (4m x 3mm) package and the 16-lead thermally enhanced TSSOP.
1000-piece pricing is $2.05 for the LT3012BEDE, $2.20 for the LT3012BEFE, $2.25 for the LT3013BEDE and $2.40 for the LT3013BEFE. Request a free brochure from Linear Technology Corp ...
