Power IC is biased about CCD imaging
The LT3487 is a dual channel (boost/inverter), 2MHz DC/DC convertor with output disconnect.
New from Linear Technology Corp is the LT3487, a dual channel (boost/inverter), 2MHz DC/DC convertor with output disconnect Its internal 750mA/900mA 30V switches can deliver up to 45mA at 15V and 90mA at -8V from a single Li-ion cell, providing bias for the latest generation of CCD (charge-coupled device) imagers

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.
Its input voltage range of 2.3 to 16V enables inputs that range from Li-ion to multiple cell alkaline/NiMH batteries.
Switching at a constant 2MHz, the LT3487 uses tiny low profile capacitors and inductors, generating low noise outputs that are easy to filter.
Schottky diodes are integrated into the IC, and output voltages can be set with only one resistor per channel, reducing external component count.
Packaged in a 3 x 3mm DFN, the entire solution has less than a 1mm profile and occupies just 50mm2.
The LT3487 offers internal sequencing circuitry that disables the negative channel until the positive channel has reached 87% of its final value.
This ensures that the sum of the two outputs is always positive.
Intelligent soft-start allows sequential soft-start of the two channels with a single capacitor.
The LT3487EDD is available from stock and pricing starts at $2.30 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
