MAXREFDES1019: Multi-Output DC-DC Converter Using Buck Regulator

This document describes a circuit that uses three MAX17541G buck converters and one MAX17504 step-down DC-DC converter. The circuit is arranged so that each buck converter uses the same input with four separate outputs. Each output has a different power specification. The MAX17541G regulator and features are given first, followed by the MAX17504 features.

Isolated shunt/voltage measurement reference design for automotive battery pack monitoring

This TI verified design provides principles, component selection, TINA-TI simulation, verification and measurement performance, Altium schematic, PCB layout for automotive battery pack monitoring applications. This design uses the automotive AEC-Q100 qualified 12-bit, 4-channel, 1Msps SAR ADC ADS7950-Q1 and isolated system hardware. This isolated input design with four-wire shunt resistors is ideal for such applications using high and low voltage automotive battery packs. It can be used to monitor battery pack current (from -5A to +5A) and extremely high voltages (up to 750V). TINA simulations on input and reference drivers validate design solutions and component selections, while measured results prove the performance of precision designs.

Smart Damper Control Reference Design with Pressure, Humidity and Temperature Sensing

This reference design is built to enable multiple room comfort control in connected HVAC systems. Sensing temperature, humidity, and pressure allows independent monitoring and air-flow adjustment in each zone. This TI Design converts a constant air volume (CAV) into a variable air volume (VAV) system. Collected data can be transmitted wirelessly to the smart thermostat or gateway. Onboard sensors can be employed to allow predictive maintenance, shorten technical troubleshooting time, and reduce overall energy consumption. Long battery life allows the smart damper to run for many years without the need to spend time and money on battery replacement.

Smart lock reference design using 4 AA batteries (lifetime over 5 years)

Wireless battery-powered smart locks are becoming more and more popular in today's market with the increasing number of building and residential owners looking to retrofit smart locks (or electronic locks) for their buildings or homes. In smart lock applications, high current motors and radios often have a faster battery drain rate, resulting in compromised battery life. Replacing multiple batteries can be time-consuming and costly, so reducing average current draw is often a key design consideration.
