Summit Microelectronics (Sunnyvale, CA) has expanded its family of programmable DC-DC integrated circuits with the SMB206A and SMB210A. The SMB206A and SMB210A support advanced power management for ENERGY STAR® applications. These include digital LCD/LED/plasma/IP televisions, digital cable/satellite/IP set-top boxes and media gateways, broadband cable/DSL modems, wireless SoHo routers, and switches.
The SMB206A/SMB210A are dual/single-output integrated DC-DC buck regulators combining digital programmability with dense integration, ultra-compact size, and cost-effective bill-of-materials (BoM) necessary for mass-market consumer products. With a serial digital interface and on-board non-volatile memory, the SMB20X family can be easily configured during development and re-programmed in system by host software. The result is a flexible, digitally controlled power supply design that is easily customizable without tedious hardware design cycles or complex microcontroller-style GPIO-based control.
