LTC7150SIY#PBF

LTC®7150S is a high efficiency monolithic synchronous buck regulator capable of delivering 20A to the load. It uses a phase lockable controlled on-time constant frequency, current mode architecture. PolyPhase operation allows multiple LTC7150S regulators to run out-of-phase, which reduces the amount of input and output capacitors required. The high frequency capability allows the use of physically smaller inductor and capacitor sizes. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that operate at high frequencies while demanding fast transient response. This uses second generation Silent Switcher technology including integrated bypass capacitors to deliver a highly efficient solution at high frequencies with excellent EMI performance. Typical applications are server power applications, distributed power systems, point of load supply for ASIC, FPGA, DSP, µP, etc.
