30-V buck regulatorMicrochip Technology Inc. announced the MCP16301 — it’s first 30-V-input, buck switching regulator with 600 mA output capability. The MCP16301 features a wide input voltage range, from 4 V to 30 V, an output voltage range from 2 V to 15 V and provides up to 95 percent efficiency. The regulator 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 appropriate 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-V to 24-VDC power rails, for use with PIC microcontrollers and other low-voltage devices. The high-speed peak current mode control allows fast responses to sudden input-voltage and load transients encountered in power applications. The regulator also delivers desirable 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 is asserted to decrease 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.
