TEA1206T

Note
1. Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.

The TEA1206T (see Fig.1) is a fully integrated DC/DC converter circuit. Efficient, compact and dynamic power conversion is achieved using a novel, digitally controlled Pulse Width and Frequency Modulation (PWFM) like control concept, integrated low R_dsON CMOS power switches with low parasitic capacitances, and fully synchronous rectification. The device operates at a high 590 kHz switching frequency which enables the use of minimum size external components. Deadlock is prevented by an on-chip undervoltage lockout circuit. Compatibility with Li-ion batteries is guaranteed by an accurate current limit function.
