SMB113 Datasheet PDF - Summit Microelectronics

INTRODUCTION
The SMB113 is a highly integrated and flexible four-channel power manager designed for use in a wide range of portable
applications. The built-in digital programmability allows system designers to custom tailor the device to suit almost any multi channel power supply application from digital camcorders to mobile phones. Complete with a user friendly GUI, all programmable settings including output voltages and input/output voltage monitoring can be customized with ease.

FEATURES & APPLICATIONS
• Digital programming of all major parameters via I2C interface and non-volatile memory
  o Output voltage set point
  o Input/Battery voltage monitoring
  o Output power-up/down sequencing
  o Digital soft-start and output slew rate
  o Output voltage margining
  o UV/OV monitoring of all outputs
  o Enable/Disable outputs independently
• User friendly Graphical User Interface (GUI)
• Four synchronous step-down (buck) output channels
• +2.7V to +6.0V Input Range
• Highly accurate reference and output voltage (<0.5%) with Active DC Output Control (ADOC™) technology
• Undervoltage Lockout (UVLO) with hysteresis
• 800 kHz operating frequency
• 96 bytes of user configurable nonvolatile memory

Applications
• Digital camcorders/still cameras
• Portable DVD/MP3/GPS
• Camera/smart phones
• Mobile Computing/PDA’s
• Consumer battery-operated equipment
