Micrel has introduced the MIC2174, the latest, premium member of its Hyper Speed Control family of adaptive on-time controllers. The device is a DC-DC controller capable of high delta-V operation (VIN = 40 V, VOUT = 0,8 V) and can drive up to 25 A of load current. The device operates at 300 kHz constant frequency and achieves greater than 94% efficiency over a broad load range. It is easy to use and is stable even with a zero-ESR output capacitor, making designs very robust and offering the ability to scale down external capacitors. The MIC2174 operates over a wide input supply range of 3 V to 40 V and also offers cycle-by-cycle current limiting for FET protection. While the UVLO circuitry ensures proper operation under power-sag conditions to prevent the MOSFETs from overheating, the soft start feature reduces the inrush current.
