TPS40170RGYR

Product Summary

The TPS40170RGYR is a full-featured, synchronous PWM buck controller that operates at an input voltage between 4.5V and 60V and is optimized for high-power-density, high-reliability DC/DC converter applications. The controller implements voltage-mode control with input-voltage feed-forward compensation that enables instant response to input voltage change. The switching frequency is programmable from 100 kHz to 600 kHz. The applications of the TPS40170RGYR include POL Modules, Wide Input Voltage, High-Power DensityDC/DC Converters for Industrial, Networkingand Telecomm Equipment.
