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 .
& APPLICATIONS
• Digital programming of all major parameters via I2C interface and non-volatile memory
• Output voltage set point
• Input/battery voltage monitoring
• Output power-up/down sequencing
• Dynamic voltage control of all outputs
• UV/OV monitoring of all outputs
• Enable/Disable outputs independently
• User friendly Graphical User Interface (GUI)
• Three synchronous step-down output channels
• Integrated RESET monitor
• +2.7V to +6.0V Input Range
• Highly accurate output voltage: <2.5%
• Factory programmable dead times
• 0% to 100% Duty Cycle operation
• Undervoltage Lockout (UVLO) .
