Microchip Announces New 30V Buck Switching Regulator

May 24, 2011 by Jeff Shepard

Microchip Technology Inc. announced the MCP16301 – Microchip’s first 30V-input, buck switching regulator with 600mA output capability. The MCP16301 features a wide input voltage range, from 4 to 30V, an output voltage range from 2 to 15V and provides up to 95% efficiency. The 600 mA MCP16301 is offered in a 6-pin SOT-23 package with an integrated high-side switch, and requires a minimal number of external components. It is Well suited for applications in the industrial, telecommunications, consumer and automotive markets, such as set-top boxes, LED lighting, HVAC systems and power meters.

The MCP16301 provides an efficient and compact solution for stepping down 12 to 24Vdc power rails, for use with PIC® microcontrollers and other low-voltage devices in a wide range of applications. The high-speed peak current mode control allows fast responses to sudden input-voltage and load transients encountered in power applications. The MCP16301 also delivers excellent line and load regulation, while the integrated control-loop compensation and slope compensation make the complex task of stabilizing the converter control system simple and reliable. Additionally, the MCP16301 decreases the power demand, and the amount of heat dissipated within the application and in the corresponding cooling requirements, when compared to a low drop-out (LDO) regulator. These decreases enable longer battery life and make meeting power requirements easier.

"The MCP16301 continues Microchip’s focus on high-efficiency power products," said Bryan J. Liddiard, Vice President of Marketing with Microchip’s Analog and Interface Products Division. "It provides our customers with yet another competitive, compact solution for a wide variety of applications. Customers can implement a complete MCP16301 solution within the footprint of a typical D2PAK LDO, while dissipating much less heat and providing higher efficiencies."

Mikhail Voroniouk, Senior Product Marketing Engineer with Microchip’s Analog and Interface Products Division, added, "The MCP16301 highlights Microchip’s commitment to providing our customers with a wide-ranging product portfolio that is focused on low power consumption."

The MCP16301 is supported by the MCP16301 300 mA D2PAK footprint Demo Board ($14.99) and the MCP16301 600 mA Demo Board ($19.99). Customers can also access a component-selection tool and the MCP16301’s application notes, both offered via free download via the company’s website.

The MCP16301 buck switching regulator is available in a 6-pin SOT-23 package for $0.83 each, in 10,000-unit quantities.
