SMB122 Datasheet (Summit Microelectronics) - Eight-Channel Programmable DC-DC Power Managers

SMB122, Eight-Channel Programmable DC-DC Power Managers

The SMB122 and SMB122X are fully-programmable power supply and battery managers that regulate, sequence, monitor, and margin, an entire power subsystem while controlling the charging of a lithium-ion battery pack.

They have 8 voltage outputs, consisting of: three synchronous PWM “Buck” step-down con
