The IM6001 is a 1A step-down power module which  integrated inductor, MOSFETs and controller in one  tiny package, perfectly suiting for any space  constrained application. Operating over an input  voltage range of 2.9V to 5.5V, the module supports  an output voltage range from 1V to V_IN by 100% duty  cycle control. For programmable output, only two FB  resistors and input and output capacitors are needed  to complete the design, while the FB resistors can be  removed in fixed output design. This results a  simplification in supply chain and inventory  management, and helps to enable an overall cost  savings.

3MHz switching frequency and constant on-time  control scheme architecture deliver a very fast  transient response to line and load changes without  sacrificing stability. It also features an internal soft-start function and offers protection features  including input UVLO, cycle-by-cycle current limit,  output short-circuit protection and thermal shutdown.
