Description

The MIC2165 is a synchronous adaptive on-time buck controller targeting high performance, cost sensitive applications such as set-top boxes, gateways, routers, computing peripherals, and telecom/networking equipment.

The MIC2165 operates over a supply range of 4.5V to 28V. It has an internal linear regulator which provides a regulated 5V supply to power the internal control circuitry. MIC2165 operates at a constant 600kHz switching frequency and can be used to drive up to 25A of output current. The output voltage is adjustable from 0.8V to 5.5V.

A unique Hyper Speed Control™ architecture enables ultra-fast transient response while reducing the output capacitance and also makes High VIN/Low VOUT operation possible.

A UVLO feature is provided to ensure proper operation under power-sag conditions to prevent the external power MOSFET from over heating. Also, a soft start feature is provided to reduce the inrush current. Short current sensing on the bottom MOSFET with hiccup mode operation ensures protection in case of an output short circuit. Further, the MIC2165 includes an EN pin to shut down the converter and a Power Good (PGOOD) pin to allow simple sequencing.

The MIC2165 is available in a 10-pin MSOP ePad package with a junction operating temperature range from -40°C to +125°C.
