SMB113A - Summit

SMB113A Four-channel Programmable DC-DC System Power Managers

The SMB113A/B and SMB117/A are fully programmable DC-DC controllers that incorporate power delivery and advanced power monitoring and control functionality. The devices integrate four synchronous “buck” stepdown controllers in a space saving package. The SMB113A uses a fixed 800kHz whereas the SMB113B uses a fixed 1MHz, the SMB117 a fixed 400kHz and the SMB1.
