The Future of Analog IC Technology MP2905 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 compensation. 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 200kHz to 500kHz.
