Operating with an input voltage range of 6 V to 42 V, the LM3150 • Programmable Switching Frequency up to 1 MHz controller features an adjustable output voltage down • No Loop Compensation Required to 0.6 V. The switching frequency is adjustable up to ® • Fully WEBENCH Enabled 1 MHz and the synchronous architecture provides for • Low External Component Count highly efficient designs. The LM3150 controller employs a constant on-time (COT) architecture with a • Constant On-Time (COT) Control proprietary emulated ripple mode (ERM) control that • Ultra-Fast Transient Response allows for the use of low ESR output capacitors, • Stable With Low ESR Capacitors which reduces overall solution size and output voltage ripple. The COT regulation architecture allows • Output Voltage PreBias Startup for fast transient response and requires no loop • Valley Current Limit compensation, which reduces external component • Programmable Soft-Start count and reduces design complexity. • Create a Custom Design Using the LM3150 with Fault protection features such as thermal shutdown, the WEBENCH Power Designer undervoltage lockout, overvoltage protection, short- circuit protection, current limit, and output voltage 2 Applications prebias start-up allow for a reliable and robust solution. • Telecom • Networking Equipment The LM3150 concept provides for an easy-to-use complete design using a minimum number of external • Routers components and TI’s WEBENCH online design tool. • Security Surveillance WEBENCH provides design support for every step of • Power Modules the design process and includes features such as external component calculation with a new MOSFET selector, electrical simulation, thermal simulation, and Build-It boards for prototyping.
