The SMB118 and SMB218 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 feature 6 voltage outputs, consisting of: three synchronous PWM “Buck” step-down converters, one configurable PWM “Boost or Buck” converter, o.
& APPLICATIONS
INTRODUCTION
• Digital programming of all major parameters via I2C interface and non-volatile memory o Output voltage setpoint/margining o Sequencing & digital soft start o Enable/Disable outputs independently o Input/Output UV/OV voltage thresholds o PWM/PFM mode
• Six programmable regulator channels with 1.5% accuracy o Three synchronous step-down (Buck) with internal PFETs o One configurable step-up (Boost) or synchronous step-down (Buck) o One step-up (Boost) o One adjustable output voltage LDO
• Programmable Linear Li-Ion Battery Charger o Precharge/fast charge/terminatio.
