Micrel has expanded its family of ‘Hyper Speed Control’ synchronous DC-DC controllers with the introduction of the MIC2166.
The device is an adaptive on-time controller capable of driving up to 25 A load current. Integrated into the IC is a VDD regulator that enables single-supply operation. Micrel's unique Hyper Speed Control architecture reduces the required output capacitance and allows for excellent transient response, while making high delta-V operation (VIN = 28 V, VOUT = 0,8 V) possible. The solution is suitable for set-top boxes, gateways, routers, computer peripherals and applications with low-voltage distributed power requirements.
The MIC2166 operates at 600 kHz switching frequency, operates over a supply range of 4,5 V to 28 V and achieves up to 95% efficiency. A UVLO feature is provided to ensure proper operation under power-sag conditions, which prevents the external power MOSFET from overheating. A digital soft start feature is included to reduce the inrush current. Short current sensing on the bottom MOSFET with hiccup ensures protection in case of output short circuit. The device includes an enable input to shut down the converter and a power good output that allows simple sequencing. It is stable with any output capacitor (zero to high ESR). The MIC2166 is available in a 10-pin ePad MSOP package with a junction operating range from -40°C to +125°C.
