ADI LTC7150SEY#PBF

Step-DownБак3.1V20V20A

Overview

The LTC7150SEY#PBF 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 LTC7150SEY#PBF regulators to run out-of-phase, which reduces the amount of input and output capacitors required. The operating supply voltage range is from 3.1V to 20V.

The operating frequency is programmable from 400kHz to 3MHz with an external resistor. The high frequency capability allows the use of physically smaller inductor and capacitor sizes. For switching noise sensitive applications, the LTC7150SEY#PBF 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. The LTC7150SEY#PBF uses second generation Silent Switcher technology including integrated bypass capacitors to deliver a highly efficient solution at high frequencies with excellent EMI performance.
