1 / 36 page  LTC3375 1 3375fa For more information www.linear.com/3375 Typical applicaTion FeaTures DescripTion 8-Channel Programmable, Parallelable 1A Buck DC/DCs 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 I2C or used in standalone mode via simple I/O with power-up defaults. The DC/DCs may be used independently or in parallel to achieve higher output currents of up to 4A per output with a shared inductor. Alarm levels for high die temperaturemayalsobeprogrammedviaI2Cwithamask- able IRQ output for monitoring DC/DC and system faults. Pushbutton ON/OFF/RESET control, power-on reset, and a watchdog timer provide flexible and reliable power-up sequencing and system monitoring. The LTC3375 is avail- able in a low profile 48-lead 7mm × 7mm QFN package. 8-Channel 1A Multioutput Buck Regulator Buck Efficiency vs Load applicaTions n 8-Channel Independent Step-Down DC/DCs n Master-Slave Configurable for Up to 4A Per Output Channel with a Single Inductor n Independent VIN Supply for Each DC/DC (2.25V to 5.5V) n All DC/DCs Have 0.425V to VIN Output Voltage Range n Precision Enable Pin Thresholds for Autonomous Sequencing (or I2C Control) n 1MHz to 3MHz Programmable/Synchronizable Oscillator Frequency (2MHz Default) n I2C Selectable Phasing (90° Steps) Per Channel n Programmable Power-On Reset/Watch Dog/ Pushbutton Timing n Die Temperature Monitor Output n 48-Lead (7mm × 7mm) QFN Package n General Purpose Multichannel Power Supplies n Industrial/Automotive/Communications L , LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
