Microchip's first 30V buck switching regulator

Microchip announces its first 30V-input buck switching regulator. The MCP16301 combines a wide input voltage range of 4V to 30V, and a 600mA output across a voltage range of 2V to 15V, with up to 95 percent efficiency. With a high-side switch integrated into the small 6-pin SOT-23 package, the MCP16301 minimises the number of external components to enable an efficient and compact solution for stepping down 12V to 24V DC 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 excellent line and load regulation. On-board control-loop compensation and slope compensation simplifies the complex task of stabilising the converter control system to provide enhanced reliability. In comparison to low drop-out (LDO) regulators, the MCP16301 offers lower power consumption, heat dissipation and cooling requirements, whilst increasing efficiency and matching the LDO's typical D2PAK footprint. These features help designers to prolong battery life and meet reduced power requirements. The MCP16301 is supported by two demo boards: the MCP16301 300 mA D2PAK footprint Demo Board (ARD00360) which is priced at $14.99, and the MCP16301 600 mA Demo Board (ADM00352), priced at $19.99. A component-selection tool and application notes are also available for free download. The MCP16301 Buck Switching Regulator is available in a 6-pin SOT-23 package and is sampling now.
