DESCRIPTION
The TK11811 is a low power, low input voltage DC-DC
converter.
TK11811
This device can be optimized for use in high or low current
applications through component selection. The output
voltage is selectable for 1.9 or 2.8 V operation and can be
trimmed to any voltage in between.
20P
The frequency of the built-in relaxation oscillator is set by
external components. The internal voltage regulator
provides a stable output voltage. Optimized Toko inductor
components are available.
