Linear Technology has introduced the LTC4009, a fast-charge 4A capable, high efficiency switchmode battery charger controller for multiple battery chemistries which minimizes power dissipation without compromising board space. The LTC4009 supports Li-Ion/Polymer, NiMH, NiCd and sealed lead acid battery chemistries in multi-cell configurations.

Linear Technology has introduced the LTC4217, a 2A integrated Hot Swap™ controller for protecting low power boards with load supply voltages ranging from 2.9V to 26.5V. Like other Hot Swap devices, the LTC4217 allows a board to be safely inserted and removed from a live backplane by limiting the amount of inrush current to the load supply during power up. Hot Swap controllers typically call for a number of supporting components.

Linear Technology has announced the LT3756, a 100V, high-side current sense DC/DC converter designed to drive high current LEDs. Its 6V to 100V input voltage range makes it ideal for a wide variety of applications, including automotive, industrial and architectural lighting. The LT3756 uses an external N-channel MOSFET and can drive up to 20 1A white LEDs from a nominal 12V input, delivering in excess of 70 watts. It incorporates a high-side curr...

Linear Technology has introduced the LTM4619, a complete dual step-down DC/DC µModule regulator system, including inductors and MOSFETs in a tiny surface mount package. The LTM4619 regulates two output voltages ranging from 0.8V to 5V at up to 4A each from an input supply of 4.5V to 26.5V (28V abs max). The outputs are regulated with 180º out-of-phase operation to minimize input ripple current, thus requiring fewer input capacitors.

Linear Technology introduced the LTC3856, a two-phase single output high efficiency (up to 95%) synchronous step-down DC/DC controller with PolyPhase® operation, differential output voltage sensing and integrated phased-lock loop (PLL) synchronization. Up to 12 phases can be paralleled and clocked out of phase to minimize input and output filtering requirements for high current applications (up to 300A). The differential amplifier provides remo...

Linear Technology has announced the H- and MP-grade versions of the LTC3890/-1. This high voltage dual output synchronous step-down DC/DC controller draws only 50µA when one output is active and 60µA when both outputs are enabled.

Linear Technology introduced the LTM4609MP, a buck-boost DC/DC uModule® system-in-a-package that is guaranteed and tested for the wide -55°C to 125°C temperature range. The LTM4609MP is designed to deliver precision regulation in demanding environments in applications such as military, avionics, heavy industrial machinery, and harsh environment sensors. These uModule devices are backed by Linear Technology's rigorous reliability and quality t...
