Description

General part information

LTC3312SA Series

The LTC3312SA features dual monolithic synchronous 6A step-down converters in a 4mm × 3mm package for space saving applications with demanding performance requirements. Using a constant frequency, peak current mode architecture at switching frequencies up to 3MHz, both bucks achieve high efficiency and fast transient response with small external components. The LTC3312SA can also be configured as a single output, 2-phase 12A step-down converter.The LTC3312SA operates in forced continuous or pulse-skipping mode for low noise, or in Burst Mode operation for high efficiency at light loads. The common switching frequency is set to a default 2MHz, programmed with an external resistor, or synchronized to an external oscillator via the MODE/SYNC pin. To reduce input ripple current, the dual converters switch 180 degrees out of phase.With an input range of 2.25V to 5.5V the LTC3312SA regulates to outputs as low as 500mV. Other features include precision enable thresholds, PGOOD signals, output overvoltage protection, thermal shutdown, and output short circuit protection. Programmable soft-start and a temperature monitor output are also included. The device is available in a low profile 22-lead 4mm × 3mm × 0.95mm LQFN package with exposed pad for low thermal resistance.APPLICATIONSServers, Telecom Power Supplies, Optical NetworkingDistributed DC Power Systems (POL)FPGA, ASIC, μP Core SuppliesIndustrial/Automotive/Communications
