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.
