30V buck switching regulator achieves 95% efficiency

30V buck switching regulator achieves 95% efficiency imageMicrochip Technology's new 30V-input MCP16301 buck switching regulator features a 600-mA output and a 4 to 30V input-voltage range. The chip integrates a high-side switch and can output a voltage of 2 to 15V. It can provide as much as 95% efficiency. High-speed peak-current-mode control allows fast responses to sudden input-voltage and load transients that power applications frequently encounter. Integrated control-loop and slope compensation make it easy to reliably stabilize the converter-control system.

The IC targets use in applications in the industrial, telecommunications, consumer, and automotive markets, such as set-top boxes, LED lighting, HVAC (heating/ventilation/air-conditioning) systems and power meters. It uses less power and dissipates less heat than a low-dropout regulator does.

A D2PAK footprint demo board with 300-mA outputs is available for $14.99, and a 600-mA demo board sells for $19.99. The MCP16301 is available in a six-pin SOT-23 package and sells for 83 cents (10,000).
