LINEAR TECHNOLOGY LTC7851IUHH-1#PBF 芯片, 直流/直流控制器, 同步降压, 1MHZ, QFN-58 新
The is a quad output, multiphase synchronous step-down voltage mode DC to DC controller with accurate current sharing in 58 pin QFN package. It employs constant frequency voltage mode architecture. It maintains excellent current balance between channels when paralleled with their internal current sharing loop. Lossless DCR or a low value RSENSE is used for output current sensing. Multiple LTC7851-1 devices can be used for high phase count operation. A very low offset, high bandwidth error amplifier, combined with remote output voltage sensing, provides excellent transient response and output regulation. The LTC7851-1 operates with a VCC supply voltage from 3V to 5.5V and is designed for step-down conversion with VIN from 3V to 27V and produces an output voltage from 0.6V to VCC to 0.5V. It is used in high current distributed power systems, DSP, FPGA and ASIC supplies and datacom, telecom and computing systems.
