Introduced the LT3579 and LT3581, which are high power monolithic switching regulators. They are integrated with 6A, 42V or 3.3A, 42V power switches, built-in fault protection and operation up to 2.5MHz

Linear Technology has developed a line of µModule isolators that simplifies the design of isolated systems by simply plugging in a module, without the need for complex barrier components. µModule isolators use magnetically coupled techniques to provide data and power isolation in a single package, without the need for external components. The LTM2881 isolated RS485/RS422 transceiver and LTM2882 dual isolated RS232 transceivers use µModule isolator technology to provide complete transceiver-plus-power solutions in 15mm × 11.25mm × 2.8mm surface mount packages.

This document describes the features and characteristics of LTC3388-1/LTC3388-3. The buck converter of this model has low quiescent current, sleep state, and standby mode, making it suitable for energy harvesting and low power applications.

Solar panels have great potential as energy harvesting power sources, but they need batteries to store the harvested power and provide continuous power during dark periods. This article discusses a unique input regulation loop for a battery charger that simplifies the process of solar panel maximum power point tracking.

ZMM 1, ZMM 100 are surface mount silicon planar Zener diodes with a maximum power dissipation of 500 mW. They have a nominal Z-voltage of 1-100 V and are housed in a MiniMELF SOD-80 glass case. They weigh approximately 0.05g and are standardly supplied on a reel.

The LTC2990 measures ambient and remote temperature, plus voltage and current, so the measurements are easily combined. Temperature sensors can be diodes or transistor sensors—remote sensor diodes are available as substrate diodes in large microprocessors.

This document describes a simplified design of an isolated power supply. By examining the primary-side flyback pulse waveform, this product does not require opto-isolators or extra transformer windings to maintain regulation, and the output voltage can be easily programmed with two resistors.

LTC4360, LTC4361 and LTC4362 are able to protect mobile devices from hot-plug transients and wrong power adapter.

The LT3692A is a monolithic, dual 3A input/output buck converter with a 3V–36V operating range. The two channels are completely independent and can have different input voltages, output voltages, current limits, power good outputs, soft-start, undervoltage lockouts and even different synchronized switching frequencies.

The LTC3113 is a single inductor buck-boost converter that offers a compact, highly efficient alternative. Internal low resistance switches allow the converter to support an impressive 3A of load current in a tiny 4mm × 5mm package. The LTC3113 offers an extended input and output operating voltage range from 1.8V to 5.5V, with peak efficiencies reaching 96%.
