Low Voltage Power Supplies
Jun 9th 2016
In this video, Linear Technology Co-founder and CTO Bob Dobkin discusses low voltage power supplies less than half a volt. Most of today's power supplies have a reference of 0.6 volts, which means the output voltage must be greater than 0.6 volts. Several years ago, Linear Technology pioneered a new type of current source ...
60V, 4A Monolithic Buck Regulator w/ Rail-to-Rail Programmable Output and Integrated Current Monitoring
Apr 12th 2016
The LTC3649 step-down regulator combines key features of a high voltage buck regulator with a complete feature set that allows for ease of use in a variety of applications. The output voltage can be programmed with one resistor from ISET to GND, or it can be programmed directly with a voltage on the ISET pin. The ...
Quad Buck Regulators in an Impossibly Small Space
Nov 11th 2015
Frequently, the power supply gets whatever board space is left over regardless of how impossibly small. Using Linear’s latest Quad Buck regulator, the LT8602, you can have four regulated outputs in an incredibly small space. The LT8602 has two high voltage buck regulators with an input voltage range of 3V to 42V. It ...
LT8471 Dual Multitopology Converter with 2A Switches - Video Product Brief
Aug 29th 2014
The LT®8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion. Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter. Capable of generating positive and negative ...
Power USB VBUS in Autos with the LT8697
Jul 15th 2013
USB sockets appear in an increasing number of car models as portable devices become more ubiquitous. The USB interface delivers power to portable devices via the 5V VBUS and ground lines. Depending on the USB version and the portable device, the VBUS sources up to 2.1A. In a car, this high VBUS current presents a challenge. ...
LTC3375 8-Ch Programmable, Parallelable 1A Buck PMIC - Video Product Brief
Mar 25th 2013
The LTC®3375 is a digitally programmable high efficiency multioutput power supply IC. The DC/DCs consist of eight synchronous buck converters (IOUT up to 1A each) all powered from independent 2.25V to 5.5V input supplies.
DC/DC enables, output voltages, operating modes, and phasing may all be independently programmed over ...
High Efficiency, Ultralow IQ, 42V, 2.5A Sync Buck Regulator
Jun 14th 2012
The LT®8610 step-down regulator integrates key high performance features in one compact IC. It offers synchronous rectification, for efficiencies up to 96%. The low quiescent current of 2.5µA extends battery life and saves extra circuitry. High speed switching minimizes board space and helps avoid EMI problems. A low dropout ...
Switching Regulator Power Loss
Jan 9th 2012
Efficiency is a misleading number for comparison of switching regulators. The efficiency number can be manipulated by the input and output voltage, while power loss is more tightly tied to the actual circuit. This video explains why.
