TD8211 High Efficiency 1MHz, 2A Step Up Regulator

The TD8211 is a fixed switching frequency (1.5MHz typical), current-mode, step-up regulator with an integrated N-channel MOSFET. The device allows the usage of small inductors and output capacitors for portable devices. The current-mode control scheme provides fast transient response and good output voltage accuracy.

The TD8211 includes under-voltage lockout, currentlimit,and over-temperature shutdown preventing damage in the event of an output overload.
