The LM315x Series controllers come with a complete package of design tools to assist with every step of the design process, including: fully supported by WEBENCH tools, external component selection including MOSFET selection, electrical and thermal simulation, and board evaluation. The LM315x Series also features external component count down to 11 components required for a complete design, and a constant on time (COT) architecture to simplify the design process. This COT architecture eliminates the need for compensation circuitry while still providing a fixed output voltage and frequency. The SIMPLE SWITCHER controller series features a synchronous architecture that allows for efficiencies up to 93% and is capable of delivering up to 12 A of output current, driving up to 1 MHz of switching frequency and supporting a wide input voltage range from 6 to 42 V.
