Microchip公司的MCP16301是高度集成高效固定频率(500kHz)的降压DC/DC转换器,其效率高达96%,输入电压4-30V,输出电压2.0V-15V,输出电压精度2%,输出电流600mA,集成了460毫欧姆的N沟MOSFET降压开关,主要用在PIC/dsPIC MCU偏压电源,24V工业输入DC/DC转换器,STB,DSL有线调制解调器,汽车电子,AC/DC数控电源,消费类电子,医疗和保健,分布电源等.本文介绍了MCP16301主要特性, 方框图,多种典型应用电路图和相应的材料清单, MCP16301高压降压转换器600mA演示板主要特性,电路图和材料清单.
The MCP16301 is a highly integrated, high-efficiency, fixed frequency, step-down DC-DC converter in a popular 6-pin SOT-23 package that operates from input voltage sources up to 30V. Integrated features include a high side switch, fixed frequency Peak Current Mode Control, internal compensation, peak current limit and overtemperature protection. Minimal external components are necessary to develop a complete step-down DC-DC converter power supply.
High converter efficiency is achieved by integrating the current limited, low resistance, high-speed N-Channel MOSFET and associated drive circuitry. High switching frequency minimizes the size of external filtering components resulting in a small solution size.
