DC1443A: Demo Board for the LTC3101 Wide VIN, Multi-Output DC/DC Converter and PowerPath Controller.

Demonstration circuit 1447A is an adjustable 200mA linear regulator featuring LT3082. Architected as a precision current source and voltage follower, it allows this new regulator to be used in many applications with adjustability to zero output. The LT3082 has an input range of 1.2V to 40V, but the demo board limits this range to 2.8V to 35V. The LT3082 withstands reverse input voltages and reverse output-to-input voltages without reverse-current flow.

The LTC3601 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying up to 1.5A of output current. The operating supply voltage range is from 4V to 15V, making it suitable for a wide range of power supply applications.The operating frequency is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors. For switching noise sensitive applications, the LTC3601 can be externally synchronized over the same frequency range. An internal phase-locked loop aligns the on-time of the top power MOSFET to the internal or external clock. This unique constant frequency/ controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response.The LTC3601 offers two operational modes: Burst Mode operation and forced continuous mode to allow the user to optimize output voltage ripple, noise, and light load efficiency for a given application. Maximum light load efficiency is achieved with the selection of Burst Mode operation while forced continuous mode provides minimum output ripple and constant frequency operation.Applications Distributed Power Systems Lithium-Ion Battery-Powered Instruments Point-of-Load Power Supply
