INTRODUCTION
The SMB119 is a highly integrated and flexible seven-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.

FEATURES & APPLICATIONS
• 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
• Seven programmable regulator channels with 1.5% accuracy
    o Three synchronous step-down (buck) with internal PFETs
    o Two step-up (boost)
    o One configurable step-up (boost) or step-down (buck)
    o One adjustable output voltage LDO
• +2.7V to +6.0V Input Range (Higher system voltages supported)
• Built-in current limiting, UV/OV, and thermal protection
• Highly accurate reference and output voltage (<1.5%)
• 1MHz PWM frequency and automatic power-saving PFM mode
• 96 bytes of user configurable nonvolatile memory
• Space-saving 7x7 QFN-48 package

Applications
