Buck regulator

6 July 2011 Power Electronics / Power Management

Microchip has rolled out its first 30 V-input buck switching regulator. The MCP16301 combines a wide input voltage range of 4 V to 30 V and a 600 mA output across a voltage range of 2 V to 15 V, with up to 95% efficiency.

With a high-side switch integrated into the small 6-pin SOT-23 package, the device minimises the number of external components needed to enable an efficient and compact solution for stepping down 12 V to 24 V d.c. power rails to drive PIC microcontrollers and other low-voltage devices. The MCP16301 is suitable for use in set-top boxes, LED lighting, HVAC systems and power meters in addition to other applications in the industrial, telecommunications, consumer and automotive markets.

The high-speed peak current mode control provides a fast response to sudden input-voltage and load transients in power applications and the MCP16301 also delivers stable line and load regulation. Onboard control-loop compensation and slope compensation simplify the complex task of stabilising the converter control system to provide enhanced reliability.
