SMB112 产品详情

INTRODUCTION

The SMB112 is a highly integrated and flexible five-channel power manager designed for powering TFT/LCD display panels and for driving low- and high-power white-LEDs. 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 set-point

  o Individual dimming

  o Output power-up/down sequencing

  o Digital soft-start and output slew rate

  o Input/Battery voltage monitoring

  o UV/OV monitoring of all outputs

  o Enable/Disable outputs independently

• Five output channels

  o One synchronous step-down (buck) channel

  o Two step-up (boost) channels

  o One inverting (buck-boost) channel

 o One fixed output +3.3V LDO

• +2.7V to +6.0V Input Range

• Highly accurate reference and output voltage (<0.5%) with Active DC Output Control (ADOC™) technology

• Supports multiple strings of up to 12 white LEDs in series

• Undervoltage Lockout (UVLO) with hysteresis

• 800 kHz operating frequency

• 96 bytes of user configurable nonvolatile memory



Applications

• White LED backlighting

• High-power LED driving

• TFT/LCD Displays/Monitors/TV’s

• Digital camcorders/still cameras

• Portable DVD/MP3/GPS

• Camera/smart phones

• Mobile Computing/PDA’s
