Summit Microelectronics Announces SMB211 Single-Channel, Synchronous DC/DC Controller, Family of Programmable Power Manager (PPM) Integrated Circuits (ICs) Expansion

The SMB211 approaches power supply design by combining flexibility, features and performance with ease-of-use. The SMB211 can be easily configured during development (on-board, non-volatile memory) and re-programmed in system by host software. The result is a high-performance digitally controlled power supply design that is easily customizable without tedious hardware design cycles or complex microcontroller-style software coding. The SMB211 combines high-performance power conversion and digital control in a single, space-saving device. The integration of advanced power control functions eliminates external components and cost, improves functionality and performance, and minimizes development time. The SMB211 integrates a synchronous DC-DC step-down (buck) converter with a useful set of digital control functions. The device’s high current drive capability allows over 10A of output, while using a wide variety of industry-standard MOSFETs. The SMB211 can operate at four different, programmable frequencies (250kHz, 500kHz, 750kHz and 1MHz) allowing optimization of efficiency and component size. Soft-start and power-on delays are also selectable to address various system requirements, especially in multi-power supply applications…
