LINEAR dn398f handbook

LINEAR dn419f handbook

The LTC3446 is a single-chip triple-output voltage regulator that integrates a 1A synchronous buck regulator and two 300mA ultra-low dropout linear regulators to provide up to three stepped-down output voltages of 3.3V, 1.8V, and 0.8V from a single input voltage.

LINEAR dn420f handbook

LINEAR dn421f handbook

This document describes the LTC4215-1 chip, which integrates three GPIO lines and an ADC to monitor the board voltage and current. It can provide switch control and status information through GPIO for power management.

LINEAR dn422f handbook

The LTC3219 9-output universal LED (ULED) driver is a small and powerful LED driver that can be programmed via the I2C bus interface to individually  grade, blink or turn on nine individual LEDs using internal logic and circuitry to drive nine 6-bit DAC-controlled LED current sources.

LINEAR dn423f handbook

The LTC6102 is an ultraprecise current sense amplifier that dramatically enhances efficiency and dynamic range. It features an input error as low as 10μV, enabling a measurement dynamic range of 16 bits while reducing power dissipation in the sense resistor.

LINEAR dn1013f handbook

This design note explains the effect of clock jitter on high speed ADCs and uses LTC2209 as an example to show how to select a proper clock to mitigate the effect of clock jitter.

LINEAR dn424f handbook

The LTC3785 is a high-efficiency, low-cost, single-ended DC/DC converter controller from Linear Technology. It uses a high-efficiency synchronous boost/buck topology and offers high efficiency, low EMI, low dropout voltage, and low start-up current. It is well-suited for battery-powered handheld applications.

LINEAR dn425f handbook

The LTC4268-1 is a solution that integrates a high-power PD interface control with an isolated flyback controller, suitable for high-power 2-pair PoE applications. It provides the same 25k signature detection resistance as standard PoE, and has low inrush current limit and high input current limit.

LINEAR dn426f handbook

This design note introduces the features and characteristics of the 6-channel SAR ADC LTC2351-14, including the sampling rate, power consumption, and package. The device is suitable for applications such as 3-phase power line monitoring, portable power line instrumentation, power factor correction, motor control, and data acquisition.

LINEAR dn427f handbook

This design note introduces the LTC2953, a pushbutton on/off controller with failsafe voltage monitoring that can be used to control DC/DC converters, power switches, or other circuits. The device can be controlled by a short or long press of the pushbutton, and it also features fault protection that can automatically turn off the power in the event of a system failure.

LINEAR dn428f handbook

This design note introduces the LTC®3526L, a 1MHz, 550mA synchronous step-up (boost) converter with a wide input voltage range of 0.7V to 5V and an output voltage range of 1.5V to 5.25V. Housed in a 2mm x 2mm DFN package, the LTC3526L has a typical startup voltage of just 700mV, with operation down to 400mV.

LINEAR dn430f handbook

The LTM4608 is a high-density power supply module with a small form factor, lightweight design, high efficiency, and low power dissipation.

LINEAR dn431 handbook

The LTC2704 is a highly integrated 16-bit, 4-channel DAC with a wide range of features designed to increase performance and simplify design.
