Summit Microelectronics SMB20X Buck Regulators
Summit Microelectronics introduced the SMB20X family of programmable power manager (PPM) integrated circuits. The SMB20X family includes the SMB207, 207A, 208, 208A, 209, 209A single- and dual-output integrated DC-DC buck regulators. The SMB20X family combines Summit’s digital programmability with dense integration, ultra-compact size, and cost-effective bill-of-materials (BoM) necessary for mass-market consumer products. The SMB20X family is available in a tiny thermally-enhanced, RoHS-compliant, lead-free 3mm X 3mm, 20-pad QFN. Available now in production quantities, the SMB20X family is priced between $1.00 each for the SMB207 to $1.40 each for the SMB208A/209A respectively in quantities of 10,000 units.
