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.
This DC/DC uModule regulator has a profile (height) of only 2.3mm and weighs a mere 0.86g.
The device operates from an input supply range of 2.35 to 5.5V, regulates an output voltage from 0.8 to 5V, and achieves 93% efficiency when converting a 3.3V input to 2.5V output at up to 4A.
With a profile of only 2.3mm, the LTM4604 is specifically designed as a compact point-of-load DC/DC solution for applications requiring ultrathin packaging such as RAID systems and single-board computers using PCI or PCI Express.
Moreover, the compact sise, low profile and light weight allow the LTM4604 to be mounted on the back side of a printed circuit board, freeing space on the top side for FPGAs, ASICs, memory and other ICs.
The LTM4604 is a complete, compact and high reliability DC/DC point-of-load solution for systems that need to step-down input supply rails such as 5, 3.3 or 2.5V or Li-ion battery with precise regulation and excellent thermal performance.
The device features a current-mode architecture for fast transient response, short-circuit protection and excellent line and load regulation.
In addition, it offers output voltage tracking for controlled ramp-up/ramp-down and supply sequencing.
Also included are a power-good output signal to indicate whether the output voltage is in or out of regulation and protection circuitry for short-circuit and overtemperature conditions.
The LTM4604 is rated for operation from -40 to +85C.
The LTM4604 is RoHS compliant and like all Linear Technology DC/DC uModule regulators, can be assembled with a standard surface mount reflow process with Pb-based or Pb-free solder paste, 1000-piece pricing is US $8.95 each. Request a free brochure from Linear Technology Corp ...
