MP2905 Datasheet | Monolithic Power Systems

The Future of Analog IC Technology 3V-28V Input, Hysteretic Synchronous Step-Down Controller DESCRIPTION The MP2905 is a hysteretic voltage-mode control, synchronous PWM buck controller. The output voltage can be regulated from 0.6V to 0.9- VIN. It achieves high output current over a wide input supply range from 3V-28V. MP2905 integrates an internal LDO regulator that makes the controller function at a wide input supply. Hysteretic voltage-mode control provides fast transient response without additional loop pensation. An adjustable soft-start prevents inrush current at turn-on. The device senses high-side switch voltage drop for hiccup current limit and short current protection. The frequency is adjustable from 200k Hz to 500k Hz. The MP2905 is available in 10-pin MSOP package, provides a very pact system solution with minimal reliance on external ponents.
