SMB214B - Summit Microelectronics

SMB214B Three-channel Programmable DC-DC System Power Managers

The SMB214A/B/C are fully programmable DC-DC controllers that incorporate power delivery and advanced power monitoring and control functionality. The devices integrate three synchronous “buck” stepdown controllers in a space saving 5x5 QFN-32 package. The SMB214A uses a fixed 400kHz whereas the SMB214B uses a fixed 800kHz, and the SMB214C a fixed 1MHz Pulse .
