LTC7151SEV#PBF

LTC7151S is a high efficiency monolithic synchronous buck regulator capable of delivering 15A to the load. It uses a phase lockable controlled on-time constant frequency, current mode architecture. PolyPhase operation allows multiple device 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. For switching noise sensitive applications, this device can be externally synchronized from 400KHz to 3MHz. The PHMODE pin allows the user control of the phase of the outgoing clock signal. 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. It is used in application such as automotive and industrial power supplies, server power applications, distributed power systems, point-of-Load Supply for ASIC, FPGA, DSP, µP, etc.
