GENERAL DESCRIPTION
The TEA1208T is a fully integrated DC/DC converter. Efficient, compact and dynamic power conversion is achieved using special digital control concepts - Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM), integrated low RDSon CMOS power switches with low parasitic capacitances, and fully synchronous rectification.

FEATURES
• Fully integrated DC/DC converter circuit
• Up-or-down conversion
• Start-up from 1.85 V input voltage
• Adjustable output voltage
• High efficiency over a wide range of loads
• Power handling capability up to 0.42 A continuous average current
• 275 kHz switching frequency
• Low quiescent power consumption
• External clock synchronization
• True current limit for Li-ion battery compatibility
• Up to 100% duty cycle in down conversion
• Undervoltage lockout
• Shut-down function
• 8-pin SO package.

APPLICATIONS
• Cellular and cordless phones, Personal Digital Assistants (PDAs) and others
• Supply voltage source for low-voltage chip sets
• Portable computers
• Battery backup supplies
• Cameras.
