The SMB206A and SMB210A are dual-, single-output dc/dc buck regulators integrated with on-board MOSFETs supplying dual 3 A (SMB206A), or single 6 A (SMB210A) output. They feature digital programmability for digital LCD, LED, plasma, and IP televisions, digital cable, satellite, and IP set-top boxes, and media gateways, broadband cable, DSL modems, wireless SoHo routers and switches.
The buck regulators feature a serial digital interface and on-board non-volatile memory, and can be configured during development and re-programmed in the system by host software. Input voltage range is +4.5 to +16 V and the output voltage extends from +0.8 to VIN , accurate to 2.5% over load, line, and temperature. They are available in 3 x 3–mm QFN packages and have an operating temperature range is –40° to +85°C. (Ea/10,000: SMB206A, $1.20; SMB210A, $1.10 — available now.)
