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.
The H grade version operates up to a junction temperature of 150C, compared with the E and I Grade versions' 125C maximum junction temperature.
The H grade parts are both tested and guaranteed to the maximum junction temperature of 150C.
They are ideal for automotive and industrial applications which are subjected to high ambient temperatures.
The LT1936's wide input range of 3.6 to 36V makes the LT1936 suitable for regulating power from a wide variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries.
For automotive applications, the LT1936 can easily operate with sub 4V inputs, necessary for automotive "cold crank" requirements.
Its 500kHz operating frequency allows the use of tiny, low cost inductors and ceramic capacitors, resulting in low, predictable output ripple.
The LT1936HMS8E is available from stock in a thermally enhanced MSOP-10 package.
Pricing starts at $3.67 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
