Product Summary
The LM3150MH is a simple switcher Controller. It is an easy to use and simplified step down power controller capable of providing up to 12A of output current in a typical application. Operating with an input voltage range of 6V-42V, the LM3150MH features an adjustable output voltage down to 0.6V. The switching frequency is adjustable up to 1 MHz and the syn- chronous architecture provides for highly efficient designs. The LM3150MH controller employs a Constant On-Time (COT) architecture with a proprietary Emulated Ripple Mode (ERM) control that allows for the use of low ESR output capacitors, which reduces overall solution size and output voltage ripple. The Constant On-Time (COT) regulation architecture allows for fast transient response and requires no loop compensation, which reduces external component count and reduces design complexity. The typical applications of the LM3150MH inlcude Telecom, Networking Equipment, Routers, Security Surveillance and Power Modules.
