Part details & applications

The LT7200S is a quad-channel, high efficiency monolithic synchronous buck regulator, capable of sinking/sourcing 5A to the load per channel. Its multichannel flexibility is ideal for powering complex systems with the compact layout. The operating supply voltage range is from 2.9V to 18V, making it suitable for various supply applications from a 3.3V, 5V to 12V supply.

The operating frequency is programmable from 400kHz to 3MHz with an external resistor, or externally synchronized for switching noise sensitive applications. The unique “phase lockable, controlled on-time, constant frequency, current mode” architecture, is ideal for high frequency, high stepdown applications while demanding fast transient responses. The high frequency capability allows smaller surface mount inductors and capacitors. The MODE/SYNC pin selects low noise Forced Continuous Mode (FCM) or high efficiency Discontinuous Mode (DCM). The PHMODE pin allows to run out-of-phase among 4 channels, which lessens the required input and output capacitors. The LT7200S uses second generation Silent Switcher technology with integrated bypass capacitors to deliver a highly efficient solution at high frequencies with excellent EMI performance.

Applications

  • Distributed Power Systems, Server Power
  • Point of Load Supply for ASIC, FPGA, Etc.
