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 constant 1.2MHz switching frequency allows designers to keep switching noise out of noise-sensitive circuitry and enables the use of tiny capacitors and inductors.
The combination of the LTC3426's high efficiency switch and tiny ThinSOT package provides high current boost capability in a very compact form factor, making it ideal for space-constrained applications.
The LTC3426's 100mohm switch provides high efficiency at heavy loads.
It can generate up to 800mA of output current at 5V from a 3.3V supply.
Antiringing circuitry reduces EMI concerns by damping the inductor while in discontinuous mode, and internal soft-start eases inrush current concerns.
The LTC3426ES6 is available from stock in a ThinSOT package.
Pricing starts at $1.75 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
