Download Datasheet Visit Manufacturer Site View Pricing & Stock

The LTC3371 is a highly flexible multi-output power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight possible power configurations via pin programmable C1-C3 pins. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock. The operating mode for all DC/DCs may be programmed for Burst Mode or forced continuous mode operation.The CT pin programs the timing parameters of four independent RST pins as well as the watchdog timer.To reduce input noise, the buck converters are phased in 90° steps. Precision enable pin thresholds facilitate reliable power sequencing. The LTC3371 is available in low profile 38-lead 5mm × 7mm QFN and TSSOP packages.
