Description
Demonstration Circuit 2375A is a dual output 350mAstep down charge pump with a watchdog timer featuringthe LTC®3256EMSE. The LTC3256 operates with a wideinput voltage range from 5.5V to 38V and is engineeredfor diagnostic coverage in ISO262262 systems. TheLTC3256 can provide up to 350mA of output current froma 12V battery with 2W less power dissipation than 2 idealLDOs. The DC2375A was populated with automotive gradecomponents for evaluation.The LTC3256 data sheet gives a complete description ofthe device, operation and application information. The datasheet must be read in conjunction with this demo manual.
