LINEAR LTC3593 Manual
This document is about LT3593, LT3593 is a white LED driver that supports 1-Wire current programming. It can drive up to 10 white LEDs in series from a single lithium-ion cell, ensuring matched LED current and eliminating the need for ballast resistors. The device has an internally compensated step-up DC/DC converter that switches at 1MHz, so it can be used with tiny, low profile external components. The LT3593 features an internal 5-bit DAC, allowing the LED current to be programmed using only one pin. The device features true output disconnect in shutdown as well as a unique high side current sense allowing it to function as a "1-wire" current source where the low side of the LEDs can be connected to the power supply, without the need for external resistors.

LINEAR LTC3225 Manual
Supercapacitors (or ultracapacitors) are increasingly being used for short-term energy storage and applications that require intermittent high energy pulses. This article introduces a power ride-through circuit application, in which a backup energy source cuts in and powers the load if the main power supply fails for a short time. In the past, this type of application was dominated by batteries, but electric double layer capacitors (EDLCs) are quickly gaining ground due to falling price-per-farad, size, and effective series resistance per capacitance (ESR/C). In a power ride-through application, series-stacked capacitors must be charged and cell-voltage balanced. Supercaps are switched into the power path when needed and the power to the load is controlled by a DC/DC converter. The LTC3225 supercapacitor charger has several features that make it a good choice for power ride-through applications. It comes in a small, 10-lead 3mm × 3mm DFN package and features programmable charging current, automatic cell voltage balancing, low drain current on the supercapacitors, and a patent pending, low noise, constant current charger.

This document introduces a new type of power management integrated circuit (PMIC) that combines fast charging, power path control, and efficient DC/DC converters. PMICs can seamlessly manage power flow from various power sources (wall adapters, USB, and batteries) to device systems and charging batteries, while maintaining current limits when necessary.
LINEAR LTC2274 Manual
The LTC2274 is a 105Msps, 16-bit ADC that simplifies the digital connection between the ADC and FPGA by replacing the usual parallel interface with a novel high speed serial interface, thus reducing the typical number of required data input/output (I/O) lines from 16 CMOS or 32 LVDS parallel data lines to a single, self-clocking, differential pair communicating at 2.1Gbps. This frees up valuable FPGA pins and board space. It also allows flexibility to route across analog and digital boundaries—in noise sensi- tive applications, the serial interface provides higher noise immunity.
LINEAR LTC3851 Manual
The LTC3851 is a synchronous step-down switching regulator controller from Linear Technology. Its input range is 4V to 38V, making it suitable for regulating power from a variety of sources, including automotive batteries, 24V industrial supplies, and unregulated wall transformers. The LTC3851 features strong onboard drivers that allow the use of high power external MOSFETs to produce output currents up to 20A with output voltages ranging from 0.8V to 5.5V. The constant frequency peak current mode control architecture provides excellent line and load regulation along with load current sharing capability and dependable cycle-by-cycle current limiting. OPTI-LOOP® compensation simplifies loop stability design and provides well-behaved regulation over a broad range of operating conditions.
